Obrzęk kończyn górnych i dłoni
Patofizjologia i mechanizm

Obrzęk kończyn górnych i dłoni jest wynikiem nadmiernego gromadzenia się płynu w przestrzeni śródmiąższowej, spowodowanego zaburzeniem równowagi między ciśnieniem hydrostatycznym a onkotycznym oraz upośledzonym drenażem limfatycznym. Kluczowe mechanizmy patofizjologiczne obejmują zwiększone ciśnienie hydrostatyczne (np. w niewydolności serca i niewydolności żylnej), zwiększoną przepuszczalność naczyń włosowatych (w stanach zapalnych), zmniejszone ciśnienie onkotyczne osocza (hipoalbuminemia w chorobach wątroby i nerek), zaburzenia drenażu limfatycznego (limfedema pierwotna i wtórna) oraz retencję sodu i wody. Warto podkreślić, że obrzęk limfatyczny początkowo ma charakter miękki i wgłębny, a z czasem staje się twardszy z powodu włóknienia tkanki podskórnej. Specyficzne zespoły, takie jak Puffy Hand Syndrome u osób z historią dożylnych iniekcji narkotyków czy POTASH (Post Ambulatory Swollen Hands) po długotrwałym marszu, mają unikalne mechanizmy patogenetyczne związane z uszkodzeniem naczyń i dysfunkcją autonomiczną.

Patofizjologia obrzęku kończyn górnych i dłoni

Obrzęk kończyn górnych i dłoni (oedema) jest stanem, w którym dochodzi do nadmiernego gromadzenia się płynu w przestrzeni śródmiąższowej tkanek. Występuje, gdy filtracja włośniczkowa przekracza możliwości drenażu limfatycznego, co prowadzi do zauważalnych objawów klinicznych1. Patogeneza tego zjawiska jest złożona i obejmuje szereg mechanizmów, które mogą działać samodzielnie lub współwystępować.

Podstawowe mechanizmy powstawania obrzęku

Obrzęk kończyn górnych i dłoni może powstawać na skutek zaburzenia równowagi pomiędzy ciśnieniem hydrostatycznym i onkotycznym w naczyniach krwionośnych oraz w przestrzeni międzykomórkowej. Do kluczowych mechanizmów patofizjologicznych należą23:

  • Zwiększone ciśnienie hydrostatyczne w naczyniach włosowatych
  • Zwiększona przepuszczalność naczyń włosowatych
  • Zmniejszone ciśnienie onkotyczne osocza (hipoalbuminemia)
  • Zwiększone ciśnienie onkotyczne w przestrzeni śródmiąższowej
  • Zaburzenia drenażu limfatycznego
  • Retencja sodu i wody

Zaburzenia krążenia jako przyczyna obrzęku

Niewydolność serca jest jedną z częstych przyczyn obrzęków kończyn górnych. W przypadku niewydolności serca dochodzi do osłabienia zdolności mięśnia sercowego do pompowania krwi, co prowadzi do zastoju krwi w naczyniach żylnych6. Ten zastój powoduje zwiększenie ciśnienia hydrostatycznego w naczyniach włosowatych, co skutkuje przemieszczaniem się płynu z naczyń do przestrzeni międzykomórkowej7. Wzrost ciśnienia w układzie żylnym jest głównym mechanizmem powstawania obrzęków w niewydolności serca8.

Niewydolność żylna to kolejny istotny mechanizm powstawania obrzęków. Uszkodzenie zastawek żylnych w kończynach górnych, określane jako przewlekła niewydolność żylna, upośledza jednokierunkowy przepływ krwi. Nieprawidłowe działanie zastawek pozwala na gromadzenie się krwi w żyłach kończyn, co prowadzi do obrzęku9. Zastój żylny zwiększa ciśnienie hydrostatyczne w kapilarach, powodując wyciek płynu do przestrzeni śródmiąższowej10.

Obrzęk limfatyczny (limfedema)

Limfedema jest spowodowane uszkodzeniem lub niedrożnością układu limfatycznego, co prowadzi do gromadzenia się płynu bogatego w białko w przestrzeni śródmiąższowej11. Układ limfatyczny jest odpowiedzialny za usuwanie białek, wody i komórek z przestrzeni międzykomórkowej. Gdy ten system zostaje upośledzony, dochodzi do gromadzenia się płynu limfatycznego12.

Limfedema może być pierwotne (uwarunkowane genetycznie) lub wtórne (nabyte). Wtórny obrzęk limfatyczny jest częstszy i może być spowodowany13:

  • Usunięciem lub uszkodzeniem węzłów chłonnych podczas leczenia nowotworów
  • Radioterapią, która prowadzi do włóknienia i blokady drenażu limfatycznego
  • Urazami układu limfatycznego
  • Infekcjami układu limfatycznego
  • Otyłością, która może zwiększać ryzyko rozwoju obrzęku limfatycznego

1415

Obrzęk limfatyczny zazwyczaj początkowo ma charakter miękki i wgłębialny (pitting edema), jednak z czasem staje się twardszy i bardziej oporny na ucisk z powodu postępującego włóknienia tkanki podskórnej16.

Zespół opuchniętej dłoni (Puffy Hand Syndrome)

Puffy Hand Syndrome to szczególny rodzaj obrzęku kończyn górnych, występujący najczęściej u osób z historią dożylnego przyjmowania narkotyków. Dokładna patogeneza tego zespołu nie jest w pełni poznana, jednak istnieje kilka hipotez wyjaśniających jego mechanizm1718:

  1. Powtarzające się iniekcje powodują zwłóknienie i uszkodzenie naczyń żylnych i limfatycznych, prowadząc do niedrożności limfatycznej19.
  2. Substancje wstrzykiwane dożylnie mogą wywoływać reakcję zapalną i tworzenie ziarniniaka podobnego do reakcji na ciało obce20.
  3. Wielokrotne infekcje skóry i tkanki podskórnej spowodowane niesterylnymi praktykami iniekcyjnymi mogą uszkadzać układ limfatyczny górnych kończyn21.

Obrzęk w tym zespole rozpoczyna się jako miękki i wgłębialny, ale z czasem staje się twardszy w wyniku postępującego włóknienia tkanki podskórnej. Początkowo obrzęk może być asymetryczny i okresowy, często dotyczący ręki niedominującej, ale z czasem staje się trwały i symetryczny22.

Zaburzenia nerkowe i wątrobowe

Choroby nerek mogą prowadzić do obrzęków kończyn górnych poprzez zatrzymywanie sodu i wody w organizmie23. Gdy nerki nie są w stanie usunąć wystarczającej ilości płynu i sodu z krwi, dochodzi do wzrostu ciśnienia w naczyniach krwionośnych, co powoduje wyciek płynu do tkanek otaczających24.

Marskość wątroby wpływa na funkcję wątroby, prowadząc do zmian w wydzielaniu hormonów i substancji regulujących gospodarkę wodną oraz zmniejszonej produkcji białek. To powoduje wyciek płynu z naczyń krwionośnych do otaczających tkanek25. W marskości wątroby dochodzi również do spadku poziomu albumin we krwi, co zmniejsza ciśnienie onkotyczne osocza i przyczynia się do powstawania obrzęków26.

Obrzęk związany z lekami

Niektóre leki mogą powodować obrzęk kończyn górnych i dłoni poprzez różne mechanizmy2728:

  • Blokery kanału wapniowego (np. amlodypina) – powodują rozszerzenie naczyń krwionośnych, co zwiększa ciśnienie w kapilarach i prowadzi do wycieku płynu29. Mechanizm obrzęku związanego z blokerami kanału wapniowego polega raczej na redystrybucji płynu z kapilar do przestrzeni śródmiąższowej niż na zatrzymywaniu płynów30.
  • Niesteroidowe leki przeciwzapalne (NLPZ) – mogą powodować uszkodzenie nerek, co prowadzi do obrzęku31.
  • Kortykosteroidy – wpływają na równowagę wodną i sodową organizmu32.
  • Leki przeciwpadaczkowe (gabapentyna, pregabalina) – mogą powodować zatrzymanie płynów33.
  • Leki przeciwdepresyjne (inhibitory monoaminooksydazy) – mogą powodować zatrzymanie płynów34.

Mechanizmy obrzęku podczas aktywności fizycznej

Obrzęk dłoni i kończyn górnych może wystąpić również podczas długotrwałej aktywności fizycznej, takiej jak marsz czy turystyka piesza. Mechanizm tego zjawiska jest wieloczynnikowy35:

  • Paski plecaka mogą uciskać naczynia krwionośne i limfatyczne w kończynach górnych, utrudniając odpływ krwi i limfy36.
  • Brak aktywnego skurczu mięśni ramion może ograniczać przepływ krwi i limfy, w przeciwieństwie do kończyn dolnych, gdzie ciągłe skurcze mięśni podczas chodzenia pomagają w przepływie płynów37.
  • Unieruchomienie dłoni podczas marszu może przyczyniać się do gromadzenia płynu38.

Zaawansowane mechanizmy patofizjologiczne obrzęku

Rola zespołu poobstrukcyjnego żylnego

Zakrzepica żył głębokich (DVT) kończyn górnych może prowadzić do obrzęku poprzez blokadę odpływu krwi żylnej. Gdy zakrzep blokuje żyłę, ciśnienie hydrostatyczne w naczyniach dystalnych do miejsca niedrożności wzrasta, powodując wyciek płynu do przestrzeni śródmiąższowej39. Podobny mechanizm może wystąpić, gdy guz uciska na żyły, upośledzając odpływ krwi z kończyny40.

Rola stanu zapalnego

Stan zapalny może przyczyniać się do powstawania obrzęku kończyn górnych poprzez zwiększenie przepuszczalności naczyń włosowatych. Zapalenie powoduje uwalnianie mediatorów zapalnych, które rozszerzają naczynia i zwiększają ich przepuszczalność, umożliwiając przechodzenie białek i płynu do przestrzeni śródmiąższowej41. Stan zapalny może być spowodowany urazem, infekcją, reakcją alergiczną lub innymi czynnikami42.

Zmiany hormonalne i metaboliczne

Ciąża może prowadzić do obrzęków kończyn górnych i dłoni poprzez uwalnianie hormonów, które sprzyjają zatrzymywaniu płynów. Podczas ciąży organizm zatrzymuje więcej sodu i wody niż zwykle, co może prowadzić do obrzęku twarzy, dłoni i kończyn dolnych43.

Cukrzyca może przyczynić się do powstawania obrzęków poprzez powikłania, takie jak choroby sercowo-naczyniowe, ostra niewydolność nerek lub ostra niewydolność wątroby44.

Mechanizmy pojawiania się obrzęku w zespole obturacyjnego bezdechu sennego

Obturacyjny bezdech senny może również powodować obrzęki45. Dokładny mechanizm nie jest w pełni poznany, ale może być związany z wahaniami ciśnienia w klatce piersiowej podczas epizodów bezdechu, co wpływa na funkcję serca i retencję płynów.

Mechanizm powstawania obrzęku POTASH

POTASH (Post Ambulatory Swollen Hands) to idiopatyczny nawracający stan obrzęku dłoni występujący po długotrwałym marszu. Patogeneza tego stanu nie została w pełni ustalona, ale proponowane mechanizmy obejmują46:

  • Zmniejszony powrót żylny z dłoni (podobnie jak u pacjentów z zespołem cieśni nadgarstka, zjawiskiem Raynauda czy zespołem górnego otworu klatki piersiowej)
  • Dysfunkcja autonomiczna
  • Systemowy efekt neurogenny
  • Nieprawidłowy ruch ramienia (z powodu nadmiernej ilości płynu przemieszczającego się do dłoni w wyniku działania siły odśrodkowej)

Mechanizm obrzęku jatrogennego po mastektomii

Obrzęk kończyny górnej po mastektomii z powodu raka piersi jest częstym powikłaniem, które może wynikać z usunięcia węzłów chłonnych pachowych lub radioterapii. Badania sugerują, że w patogenezie tego obrzęku mogą występować zarówno zaburzenia limfatyczne jak i żylne, a co interesujące, w niektórych przypadkach zmiany mogą być obustronne47.

Podsumowanie mechanizmów patofizjologicznych

Obrzęk kończyn górnych i dłoni może być wynikiem złożonych i nakładających się mechanizmów patofizjologicznych. Kluczowe procesy to4849:

  1. Zaburzenia krążenia – zwiększone ciśnienie hydrostatyczne w naczyniach włosowatych na skutek niewydolności serca, niewydolności żylnej lub zakrzepicy.
  2. Zaburzenia limfatyczne – upośledzony drenaż limfatyczny spowodowany uszkodzeniem lub niedrożnością naczyń limfatycznych.
  3. Zmniejszone ciśnienie onkotyczne osocza – najczęściej z powodu hipoalbuminemii w chorobach wątroby, nerek lub w stanach niedożywienia.
  4. Zwiększona przepuszczalność naczyń – w stanach zapalnych, infekcjach lub jako skutek działania toksyn.
  5. Retencja sodu i wody – w chorobach nerek, niewydolności serca lub jako skutek działania niektórych leków.

Zrozumienie mechanizmów patofizjologicznych obrzęku kończyn górnych i dłoni jest kluczowe dla właściwej diagnostyki i skutecznego leczenia tego stanu. Leczenie powinno być ukierunkowane na przyczynę podstawową, a nie tylko na objawy50.

    Edema is an accumulation of fluid in the interstitial space that occurs as the capillary filtration exceeds the limits of lymphatic drainage, producing noticeable clinical signs and symptoms. […] The accumulation of fluid occurs when local or systemic conditions disrupt this equilibrium, leading to increased capillary hydrostatic pressure, increased plasma volume, decreased plasma oncotic pressure (hypoalbuminemia), increased capillary permeability, or lymphatic obstruction. […] Edema associated with decreased plasma oncotic pressure (e.g., malabsorption, liver failure, nephrotic syndrome) does not change with dependency. […] Unilateral swelling from compression or compromise of venous or lymphatic drainage can result from DVT, venous insufficiency, venous obstruction by tumor, lymphatic obstruction, or lymphatic destruction.

    Edema results from increased movement of fluid from the intravascular to the interstitial space or decreased movement of water from the interstitium into the capillaries or lymphatic vessels. The mechanism involves one or more of the following: […] Increased capillary permeability occurs in infections or as the result of toxin or inflammatory damage to the capillary walls. […] The lymphatic system is responsible for removing protein and white blood cells (along with some water) from the interstitium. Lymphatic obstruction allows these substances to accumulate in the interstitium. […] Decreased plasma oncotic pressure often triggers secondary sodium and water retention, leading to fluid overload.

    Edema refers to swelling due to fluid buildup in bodily tissues. It most often occurs in the skin, especially in the hands, arms, ankles, legs, and feet. […] Peripheral edema: This affects the feet, ankles, legs, hands, and arms. Symptoms include swelling, puffiness, and difficulty moving certain body parts. […] Edema can result from circulatory problems, infection, tissue death, malnutrition, total body fluid overload, and electrolyte problems. […] If one or both of the lower chambers of the heart cannot pump blood properly, blood can accumulate in the limbs, causing edema. […] The body of a person with a kidney disorder may not be able to eliminate enough fluid and sodium from the blood. This puts pressure on the blood vessels, which causes some of the liquid to leak out. Swelling can occur around the legs and eyes.
  • #7 Heart failure and edema: Treatment and life expectancy

    Edema is a common complication of heart failure. […] This elevation in pressure forces fluid out of the blood vessels and into the surrounding tissues, resulting in swelling, or edema. […] Either type of heart failure can lead to edema. […] Lower limb edema is a hallmark symptom of heart failure. […] The most common form of edema in heart failure is not serious in itself. However, edema can indicate that heart failure is advanced or getting worse. […] A 2021 review of past studies suggests that increased edema may predict worsening heart failure. […] Edema can occur in the later stages of heart failure, but it does not always indicate a person is in the final stage of heart failure. […] As a result, people can have edema in several stages. However, very obvious or worsening edema is more likely to happen in the later stages.

    Edema (or „oedema”) means swelling. It arises when part of the body becomes swollen because fluid gathers in the tissue. It is most common in the arms and legs. That is called peripheral edema. […] Heart failure (cardiac insufficiency) can cause edema in the arms and legs (peripheral edema) as well as in the abdomen (ascites). This is because the heart is too weak to pump blood around the body properly, so the blood gathers in front of the heart. As a result, and due to the increased blood pressure in the veins, fluid seeps out into the surrounding tissue. This may cause swelling in the legs or a build-up of fluid in the abdomen. […] Kidney disease can cause edema in the legs and around the eyes. This is because the pressure in the blood vessels starts building up if the kidneys don’t remove enough sodium and water from the body, and that can lead to edema.

    https://www.mayoclinic.org/diseases-conditions/edema/symptoms-causes/syc-20366493
    Edema occurs when tiny blood vessels in the body, also known as capillaries, leak fluid. The fluid builds up in nearby tissues. The leak leads to swelling. […] Symptoms of edema include: Swelling or puffiness of the tissue right under the skin, especially in legs or arms. […] Congestive heart failure causes one or both of the heart’s lower chambers stop pumping blood well. As a result, blood can back up in the legs, ankles and feet, causing edema. […] Weakness or damage to veins in your legs. This condition, known as chronic venous insufficiency, harms the one-way valves in the leg. One-way valves keep blood flowing in one direction. Damage to the valves allows blood to pool in the leg veins and causes swelling. […] Problems with the system in the body that clears extra fluid from tissues. If the body’s lymphatic system is damaged, such as by cancer surgery, the lymphatic system might not drain well.

    https://www.healthhype.com/swollen-arm-swelling-of-the-hand-forearm-fingers.html
    Swelling anywhere in the body is due to fluid accumulation. This fluid may be tissue fluid or blood. Normally there is a constant inflow and outflow of these fluids. However, when there is inflammation then more fluid flows in to the arm and this fluid accumulates in the tissue spaces. This causes swelling of the arm. Inflammation is the mechanism by which the body protects against tissue damage. It does not only occur in the arm. […] Another reason for swelling is where blood accumulates in the tissue spaces. This may be seen as a red to purple bruising if it occurs under the skin. It signals a break in a blood vessel that allows the blood to flow out of the artery or vein. Similarly blood is constantly drained out of the arm through the veins. However, if the vein is blocked then the blood can accumulate in the arm and cause it to become swollen.

    The lymphatics are destroyed; tissue protein increases, causing excessive connective tissue growth and resulting in fibrosis. […] Del Giudice and associates stated that injected drugs cause a dermal inflammatory reaction, resulting in granuloma formation similar to a foreign body type granuloma or nonspecific granulomatous reaction. […] The prevalence of HCV infection is up to 75% in injected drug users; the majority manifest chronic disease. […] Risk factors for puffy hands among injection drug users with HCV infection are female sex, injection into the hands, and not using a tourniquet. […] Lymphedema results from accumulation of proteinaceous fluid in interstitial tissue; with time, there is inflammation and fibrosis of subcutaneous tissue. […] The cause of lymphedema can be primary or secondary. Primary conditions are differentiated by age and are hereditary or spontaneous disorders of lymphatic architecture.

    Edema is the medical term for swelling. It happens when extra fluid is trapped in the body’s tissues. […] It most commonly occurs in the hands and feet but may also affect your legs, ankles, and arms. […] Lymphedema is swelling caused by a buildup of lymph fluid. […] There are two types of lymphedema: Primary: This is caused by genetics and is much rarer. Secondary: This is more common and is acquired, which means it’s caused by trauma to the lymphatic system. Some examples include lymph node removal or damage during cancer treatment. […] Other symptoms of lymphedema may include: swelling and aching in the arm or hand, a heavy feeling in the arm, numbness in the arm or hand, skin feels tight or taut on the arm, jewelry seems to be too tight, decreased ability to flex or move your arm, hand, or wrist.
  • #14 Lymphedema and Cancer – Side Effects – NCI
    https://www.cancer.gov/about-cancer/treatment/side-effects/lymphedema
    Lymphedema is swelling caused by a buildup of lymph fluid in the body between the skin and muscle. […] If you have cancer, the cancer or cancer treatment can disrupt the flow of lymph fluid and cause lymphedema (also known as secondary lymphedema). […] Anything that blocks or changes the flow of lymph fluid in the body can cause lymphedema. Cancer and cancer treatments can cause lymphedema when: cancer or a tumor blocks the flow of lymph fluid, surgery for cancer disrupts the flow of lymph fluid, radiation therapy causes scar tissue that blocks the flow of lymph fluid. […] Lymphedema can occur anywhere in the body, but it most commonly affects an arm or leg. […] The type of cancer you have can help predict where you may develop lymphedema. […] Lymphedema in your arm or leg may cause these additional signs and symptoms: a heavy, full, or tight feeling in your arm, leg, fingers, or toes; swelling in an arm or leg that makes it appear larger than the other arm or leg; difficulty moving your arm or leg; weakness in your arm or leg.

    A 37-year-old man presented to the rheumatology clinic for evaluation of swelling of his fingers and hands. The precise pathogenesis of puffy hand syndrome remains unknown. Hand edema, which is initially pitting, becomes more indurated over time, as there is progressive fibrosis of the subcutaneous tissues. The swelling is asymmetric and intermittent at first, often affecting the nondominant hand; over time, it becomes persistent and symmetric, as in this patient. […] Repeated injection of agents that can induce vascular and dermal sclerosis results in an inflammatory reaction with granuloma formation, similar to a foreign-body granulomatous reaction. Over time, the dense dermal fibrosis obscures the superficial veins and the extensor tendons on the dorsum of the hands. […] This study indicated that puffy hand syndrome results primarily from lymphatic obstruction, and that there may be concomitant local scarring resulting from inflammatory reactions at injection sites. Venous obstruction does not appear to play a primary role but can coexist in some cases. Repeated insults are needed for swelling to develop.

    Hand edema, or puffy hand syndrome, is seen frequently in primary care practice, and given its broad differential diagnosis, presents physicians a significant diagnostic challenge. […] Another common but frequently overlooked diagnosis is hepatitis C virus (HCV) infection, which often is seen in former heroin addicts whose previous habit resulted in isolated hand edema (aka hep C hands). […] The pathogenesis of hand edema in HCV infection has not been identified definitively. When first described by Abeles in 1965, this variation of hand edema was attributed to poor venous return because of thrombosis of antecubital veins after years of injected drug use. […] Schneiderman suggested that the cause is lymphedema associated with the sclerosing properties of the drugs.

    Puffy hand syndrome associated with IVDU is a clinical diagnosis of exclusion based on a suggestive history and after consideration of other etiologies that may be progressive without treatment (eg, SLE, inflammatory arthritis, etc.). […] The suggested pathogenesis of puffy hand syndrome is that repeated trauma from venipuncture and injection of caustic substances can produce vascular and dermal sclerosis, which over time obstructs venous return. […] It is also hypothesized that the history of injection of toxic substances can damage and impair lymphatic drainage of the hands as well. […] Repeated, subcutaneous and skin infections from non-sterile injection practices may also play a role in compromising the upper extremitys lymphatic system and impede lymphatic drainage. […] In patients who undergo diagnostic testing with puffy hand syndrome, lymphangiograms typically show the presence of collateralization due to destruction of deep channels of venous drainage. […] Additionally, skin biopsies show extensive fibrosis. […] In 1 study, findings of musculoskeletal ultrasound in puffy hand syndrome suggested the only expected abnormal finding to be diffuse, subcutaneous edema.

    Edema refers to swelling due to fluid buildup in bodily tissues. It most often occurs in the skin, especially in the hands, arms, ankles, legs, and feet. […] Peripheral edema: This affects the feet, ankles, legs, hands, and arms. Symptoms include swelling, puffiness, and difficulty moving certain body parts. […] Edema can result from circulatory problems, infection, tissue death, malnutrition, total body fluid overload, and electrolyte problems. […] If one or both of the lower chambers of the heart cannot pump blood properly, blood can accumulate in the limbs, causing edema. […] The body of a person with a kidney disorder may not be able to eliminate enough fluid and sodium from the blood. This puts pressure on the blood vessels, which causes some of the liquid to leak out. Swelling can occur around the legs and eyes.

    Edema (or „oedema”) means swelling. It arises when part of the body becomes swollen because fluid gathers in the tissue. It is most common in the arms and legs. That is called peripheral edema. […] Heart failure (cardiac insufficiency) can cause edema in the arms and legs (peripheral edema) as well as in the abdomen (ascites). This is because the heart is too weak to pump blood around the body properly, so the blood gathers in front of the heart. As a result, and due to the increased blood pressure in the veins, fluid seeps out into the surrounding tissue. This may cause swelling in the legs or a build-up of fluid in the abdomen. […] Kidney disease can cause edema in the legs and around the eyes. This is because the pressure in the blood vessels starts building up if the kidneys don’t remove enough sodium and water from the body, and that can lead to edema.

    Cirrhosis affects liver function. It can lead to changes in the secretion of hormones and fluid-regulating chemicals and reduced protein production. This causes fluid to leak out of the blood vessels into surrounding tissue. […] During pregnancy, the body releases hormones that encourage fluid retention. The body also retains more sodium and water than usual. The face, hands, lower limbs, and feet may swell. […] Some complications of diabetes include cardiovascular disease, acute renal failure, acute liver failure, and protein-losing enteropathy, which is an intestinal condition that causes protein loss. […] Some causes of swelling in the brain include head injuries, stroke, and brain tumors. […] Certain medications can also increase the risk of edema. […] Edema can indicate one of many health conditions. These can range in severity, so it is important for a person to check with a doctor if they notice any unexplained swelling. […] Treatment will also depend on the cause of edema. […] Diuretics are a type of medication. They help eliminate excess fluid by increasing the rate of urine production by the kidneys. […] Edema occurs when fluid builds up in the body. This causes swelling, which can sometimes be painful.

    Low protein levels in the blood: If there’s a lack of the protein albumin in the blood, fluid can leak out of blood vessels more easily. This lack of protein can be caused by extreme malnutrition. It can also be caused by kidney and liver diseases where the body loses too much protein or produces too little protein. […] Liver diseases: Scarring of liver tissue (liver cirrhosis) for instance, due to long-term alcohol abuse or a liver inflammation can cause edema in the abdomen (called ascites). This is because cirrhosis leads to a lack of proteins and a build-up of blood in the liver, which can increase the pressure in the blood vessels. As a result, fluid seeps out into the abdomen. […] Severe lung diseases like emphysema can also cause edema in the legs and feet because the pressure in the lungs increases a lot. Blood builds up in the heart and veins.

    Lastly, medications can also be responsible for edema. There is no doubt about the wonders that modern medicine can deliver; unfortunately, edema is a common side effect of certain medications. […] Nonsteroidal anti-inflammatory drugs like ibuprofen (Motrin, Advil) and naproxen (Naprosyn, Aleve) are commonly used to treat mild to moderate pain, inflammation, and fever. Especially at higher doses of NSAIDs, prolonged use of these commonly-used drugs can cause kidney injury, which, in turn, causes edema. […] Corticosteroids like prednisone and methylprednisolone can affect the bodys water balance and salt, leading to edema. […] Drugs used to treat type 2 diabetes, such as pioglitazone and rosiglitazone, can cause swelling of the lower extremities (e.g., leg swelling) by increasing salt reabsorption in the kidneys.

    https://www.verywellhealth.com/can-norvasc-make-my-ankles-swell-1124056
    Amlodipine, sold as a generic drug or as the Katerzia and Norvasc brands, often causes ankle edema. This is an abnormal swelling of tissues due to fluid buildup. Swollen feet are a common side effect experienced by about 16% of people who use it, according to a 2019 study. […] Amlodipine is a calcium channel blocker, a medication used to treat hypertension (high blood pressure) and angina (heart-related chest pain). It relaxes blood vessels and decreases blood pressure, making it easier for your heart to pump blood throughout the body. Its effects also make it easier for the swelling to occur. […] Amlodipine and other calcium channel blockers cause blood vessels to dilate. The dilation, in turn, lowers the blood pressure and improves blood flow throughout the body. […] However, the improved blood flow can increase the pressure within smaller blood vessels called capillaries. This can cause fluids to seep through the walls of the vessels into surrounding tissues.
