Hiperglikemia w cukrzycy
Objawy

Hiperglikemia w cukrzycy definiowana jest jako podwyższony poziom glukozy we krwi, zwykle powyżej 180-200 mg/dl (10-11,1 mmol/l), przy czym objawy kliniczne rozwijają się stopniowo i mogą być różne w zależności od typu cukrzycy. W cukrzycy typu 1 objawy pojawiają się gwałtownie, natomiast w typie 2 rozwijają się powoli i często pozostają niezauważone przez długi czas. Wczesne symptomy obejmują poliurię, polidypsję, polifagię, niewyraźne widzenie oraz zmęczenie. Nieleczona hiperglikemia może prowadzić do poważnych stanów zagrożenia życia, takich jak kwasica ketonowa (DKA) i hiperosmolarny stan hiperglikemiczny (HHS), charakteryzujące się m.in. obecnością ketonów, odwodnieniem, zaburzeniami świadomości i kwasicą metaboliczną. Monitorowanie glikemii za pomocą glukometrów, CGM oraz oznaczeń HbA1c jest kluczowe dla wczesnego wykrywania i kontroli hiperglikemii, a wartości glukozy powyżej 250-300 mg/dl wymagają pilnej interwencji medycznej.

Objawy hiperglikemii w cukrzycy

Hiperglikemia w cukrzycy to stan, w którym poziom glukozy we krwi jest zbyt wysoki. Zazwyczaj hiperglikemia nie powoduje objawów, dopóki stężenie glukozy we krwi nie przekroczy znacząco wartości 180-200 mg/dl (10-11,1 mmol/l). Objawy hiperglikemii rozwijają się powoli przez kilka dni lub tygodni. Im dłużej poziom cukru we krwi pozostaje wysoki, tym poważniejsze mogą stać się objawy. Należy jednak zaznaczyć, że niektóre osoby, które od dawna chorują na cukrzycę typu 2, mogą nie wykazywać żadnych objawów mimo podwyższonego poziomu cukru we krwi.123

Wczesne objawy hiperglikemii

Rozpoznanie wczesnych objawów hiperglikemii może pomóc w szybszym zidentyfikowaniu i leczeniu tego stanu. Wśród najczęstszych wczesnych objawów hiperglikemii wyróżnia się:123

  • Częste oddawanie moczu (poliuria)
  • Zwiększone pragnienie (polidypsja)
  • Niewyraźne widzenie
  • Uczucie osłabienia lub niezwykłe zmęczenie
  • Zwiększony apetyt (polifagia)
  • Bóle głowy

Poliuria i polidypsja występują, gdy wysoki poziom glukozy we krwi powoduje przemieszczanie się glukozy do moczu, zabierając ze sobą wodę, sól i minerały.1 Stopniowo, wraz ze wzrostem poziomu cukru we krwi, objawy mogą narastać i stawać się coraz bardziej zauważalne dla pacjenta.2

Zaawansowane objawy hiperglikemii

Jeśli hiperglikemia nie jest leczona, może prowadzić do powstawania toksycznych kwasów, zwanych ketonami, które gromadzą się we krwi i moczu. Stan ten nazywany jest kwasicą ketonową. Objawy kwasicy ketonowej obejmują:123

  • Owocowy zapach z ust
  • Suchość w ustach
  • Ból brzucha
  • Nudności i wymioty
  • Duszność
  • Splątanie
  • Utrata przytomności

U niektórych osób z cukrzycą typu 2 bardzo wysoki poziom glukozy we krwi może prowadzić do zagrażającego życiu stanu zwanego hiperosmolarnym stanem hiperglikemicznym (HHS), który powoduje głębokie odwodnienie i zmianę stanu psychicznego.12

Postęp hiperglikemii w cukrzycy

Hiperglikemia w cukrzycy może mieć różny przebieg w zależności od typu cukrzycy, czasu trwania choroby oraz indywidualnych czynników pacjenta. Zrozumienie progresji hiperglikemii jest kluczowe dla skutecznego zarządzania chorobą i zapobiegania długoterminowym powikłaniom.1

Rozwój objawów w czasie

Objawy hiperglikemii rozwijają się stopniowo na przestrzeni dni lub tygodni. Intensywność i tempo rozwoju objawów mogą się różnić w zależności od typu cukrzycy:12

  • W cukrzycy typu 1 objawy często pojawiają się nagle i dramatycznie, mogą rozwinąć się w ciągu kilku tygodni.
  • W cukrzycy typu 2 objawy mogą być subtelne i rozwijać się powoli przez miesiące lub lata, co sprawia, że choroba może pozostać niezdiagnozowana przez długi czas.

Warto zauważyć, że wielu pacjentów może nie doświadczać objawów, dopóki poziom glukozy we krwi nie osiągnie wartości znacznie przekraczających normę, zwykle powyżej 250 mg/dl.1

Fazy hiperglikemii

Przebieg hiperglikemii można podzielić na kilka faz:12

  1. Łagodna hiperglikemia – charakteryzuje się wartościami glukozy powyżej normy, ale poniżej poziomu wywołującego wyraźne objawy. Pacjenci mogą nie zauważać żadnych objawów w tej fazie.
  2. Umiarkowana hiperglikemia – wraz ze wzrostem poziomu glukozy pojawiają się typowe objawy jak zwiększone pragnienie, częste oddawanie moczu i zmęczenie.
  3. Ciężka hiperglikemia – gdy poziom glukozy utrzymuje się na bardzo wysokim poziomie, mogą pojawić się poważniejsze objawy, takie jak niewyraźne widzenie, skrajne pragnienie, ospałość i skóra gorąca, zaczerwieniona i sucha.

U osób z cukrzycą typu 1 i niektórych osób z cukrzycą typu 2, które wytwarzają bardzo mało insuliny lub wcale jej nie wytwarzają, mogą wystąpić dodatkowe objawy:1

  • Szybki, głęboki oddech
  • Szybki puls i słabe tętno
  • Silny, owocowy zapach oddechu
  • Utrata apetytu, ból brzucha i/lub wymioty

Czynniki wpływające na postęp hiperglikemii

Na progresję hiperglikemii wpływa wiele czynników, w tym:12

  • Niewystarczająca ilość insuliny lub nieefektywne działanie insuliny
  • Nieodpowiedni plan żywieniowy lub spożywanie zbyt dużej ilości węglowodanów
  • Brak aktywności fizycznej
  • Stres lub choroba
  • Przyjmowanie leków, które mogą podnosić poziom cukru we krwi (np. steroidy)
  • Problemy z urządzeniami do podawania insuliny

Progresja do stanów zagrażających życiu

Nieleczona hiperglikemia może prowadzić do dwóch poważnych stanów zagrażających życiu:123

  1. Cukrzycowa kwasica ketonowa (DKA) – rozwija się, gdy w organizmie nie ma wystarczającej ilości insuliny. W tej sytuacji glukoza nie może wejść do komórek w celu dostarczenia energii, a poziom cukru we krwi wzrasta. Organizm zaczyna rozkładać tłuszcz jako źródło energii, co prowadzi do produkcji ketonów i zakwaszenia krwi. Objawia się to wymiotami, bólem brzucha, trudnościami w oddychaniu i może prowadzić do śpiączki cukrzycowej, która może zagrażać życiu.
  2. Hiperosmolarny stan hiperglikemiczny (HHS) – stan ten występuje, gdy poziom glukozy we krwi jest bardzo wysoki, ale nie ma produkcji ketonów. HHS rozwija się powoli w ciągu dni lub tygodni i jest bardziej powszechny u osób starszych z cukrzycą typu 2. Objawy obejmują ekstremalnie wysokie poziomy glukozy we krwi, poważne odwodnienie i często zaburzenia świadomości.

Długoterminowe powikłania nieleczonej hiperglikemii

Utrzymywanie poziomu cukru we krwi w zdrowym zakresie może pomóc zapobiec wielu powikłaniom związanym z cukrzycą. Długotrwała hiperglikemia, która nie jest leczona, może prowadzić do poważnych powikłań zdrowotnych, wpływających na różne układy i narządy.123

Powikłania naczyniowe

Przewlekła hiperglikemia może powodować uszkodzenie naczyń krwionośnych, prowadząc do:123

  • Chorób sercowo-naczyniowych – zwiększone ryzyko zawału serca, udaru mózgu i choroby niedokrwiennej serca
  • Choroby naczyń obwodowych – problemy z krążeniem, szczególnie w nogach i stopach
  • Mikroangiopatii – uszkodzenie małych naczyń krwionośnych, które może wpływać na różne narządy, w tym oczy, nerki i nerwy

Powikłania narządowe

Długotrwała hiperglikemia może prowadzić do uszkodzenia różnych narządów i układów:123

  1. Uszkodzenie nerwów (neuropatia):
    • Obwodowa neuropatia – drętwienie, mrowienie, ból i zmniejszona czułość, głównie w stopach i nogach
    • Neuropatia autonomiczna – problemy z funkcjonowaniem organów wewnętrznych, takich jak układ trawienny, sercowo-naczyniowy i moczowo-płciowy
  2. Uszkodzenie nerek (nefropatia cukrzycowa):
    • Postępujące uszkodzenie nerek prowadzące do niewydolności nerek
    • Konieczność dializy lub przeszczepu nerki w zaawansowanych przypadkach
  3. Uszkodzenie oczu (retinopatia cukrzycowa):
    • Uszkodzenie naczyń krwionośnych siatkówki
    • Postępujące pogorszenie wzroku, które może prowadzić do ślepoty
    • Zwiększone ryzyko zaćmy i jaskry

Powikłania stopy cukrzycowej

Problemy ze stopami spowodowane uszkodzeniem nerwów lub słabym przepływem krwi mogą prowadzić do poważnych infekcji skóry, owrzodzeń i, w niektórych ciężkich przypadkach, amputacji.12

Problemy te obejmują:

  • Zmniejszoną czułość stóp, co zwiększa ryzyko urazów
  • Słabe gojenie się ran i zwiększoną podatność na infekcje
  • Zmiany w kształcie stopy i rozwój deformacji
  • Owrzodzenia stóp, które mogą prowadzić do poważnych infekcji

Inne powikłania

Oprócz wymienionych powyżej, przewlekła hiperglikemia może również prowadzić do:123

  • Gastroparezy – opóźnione opróżnianie żołądka, co może powodować nudności, wymioty i problemy z trawieniem
  • Zwiększonej podatności na infekcje – w tym infekcje dróg moczowych, skóry i dziąseł
  • Problemów z gojeniem się ran – rany goją się wolniej i są bardziej podatne na infekcje
  • Zaburzeń funkcji poznawczych – długotrwała hiperglikemia może wpływać na funkcjonowanie mózgu i zwiększać ryzyko demencji naczyniowej

Wpływ hiperglikemii na jakość życia

Nieleczona lub przewlekła hiperglikemia może znacząco wpłynąć na jakość życia osób z cukrzycą. Kilka badań wykazało, że nieleczona przewlekła hiperglikemia skraca długość życia i pogarsza jego jakość.12

Wpływ na codzienne funkcjonowanie może obejmować:123

  • Przewlekłe zmęczenie – hiperglikemia może powodować uczucie skrajnego zmęczenia, co utrudnia wykonywanie codziennych czynności
  • Częste oddawanie moczu – może zaburzać sen i codzienne aktywności
  • Problemy ze wzrokiem – niewyraźne widzenie może wpływać na zdolność do czytania, prowadzenia pojazdu i innych czynności
  • Drętwienie i mrowienie w kończynach – może utrudniać ruchy precyzyjne i powodować dyskomfort
  • Częste infekcje – mogą wymagać interwencji medycznej i zakłócać normalną aktywność
  • Problemy ze skórą – sucha lub swędząca skóra, częste infekcje skóry i wolno gojące się rany
  • Zaburzenia seksualne – przewlekła hiperglikemia może prowadzić do uszkodzenia nerwów w narządach płciowych
  • Problemy z płodnością – trudności z poczęciem mogą być objawem wysokiego poziomu glukozy we krwi
  • Zmiany nastroju – wahania poziomu cukru we krwi mogą powodować zmiany nastroju i zachowania

Wpływ na psychikę

Życie z hiperglikemią może również mieć znaczący wpływ na zdrowie psychiczne, powodując:13

  • Stres związany z zarządzaniem chorobą
  • Lęk przed powikłaniami
  • Depresję związaną z chronicznym charakterem choroby
  • Poczucie winy lub frustrację, gdy poziomy glukozy są trudne do kontrolowania

Różnice w objawach hiperglikemii między typami cukrzycy

Objawy hiperglikemii mogą różnić się w zależności od typu cukrzycy. Nasilenie objawów jest zwykle bardziej intensywne w cukrzycy typu 1 niż w cukrzycy typu 2.12

Hiperglikemia w cukrzycy typu 1

W cukrzycy typu 1 objawy hiperglikemii mogą rozwijać się szybko w ciągu kilku tygodni lub miesięcy. Pacjenci często prezentują wyraźne objawy hiperglikemii, a czasami cukrzycowej kwasicy ketonowej (DKA).123

Charakterystyczne cechy hiperglikemii w cukrzycy typu 1:

  • Szybszy rozwój objawów
  • Bardziej wyraźne objawy, takie jak poliuria, polidypsja i utrata masy ciała
  • Większe ryzyko rozwoju kwasicy ketonowej
  • Dodatkowe objawy, które mogą obejmować nudności, wymioty, bóle brzucha

Hiperglikemia w cukrzycy typu 2

W cukrzycy typu 2 objawy mogą być subtelne i rozwijać się powoli przez lata. Wielu pacjentów może nie zauważać żadnych objawów, dopóki choroba nie zostanie zdiagnozowana podczas rutynowych badań krwi.123

Charakterystyczne cechy hiperglikemii w cukrzycy typu 2:

  • Powolny, stopniowy rozwój objawów
  • Objawy mogą być łagodne lub nawet niezauważalne przez długi czas
  • Zwiększone pragnienie i częste oddawanie moczu są zwykle łagodne na początku i stopniowo nasilają się przez tygodnie lub miesiące
  • Pacjenci mogą odczuwać skrajne zmęczenie, mieć niewyraźne widzenie i być odwodnieni
  • Mniejsze ryzyko kwasicy ketonowej, ale większe ryzyko hiperosmolarnego stanu hiperglikemicznego (HHS)

Hiperglikemia w cukrzycy ciążowej

Hiperglikemia może również wystąpić u kobiet w ciąży z cukrzycą ciążową. Chociaż objawy mogą być podobne do tych występujących w innych typach cukrzycy, hiperglikemia w ciąży wymaga szczególnej uwagi ze względu na potencjalny wpływ na matkę i dziecko.1

Kobiety z cukrzycą ciążową mogą doświadczać:

  • Zwiększonego pragnienia i częstego oddawania moczu (które mogą być trudne do odróżnienia od normalnych objawów ciąży)
  • Zmęczenia
  • Nawracających infekcji, takich jak zakażenia dróg moczowych i infekcje grzybicze

Monitorowanie glikemii i rozpoznawanie objawów

Regularne monitorowanie poziomu glukozy we krwi jest kluczowe dla osób z cukrzycą, ponieważ umożliwia wczesne wykrycie hiperglikemii, zanim pojawią się poważne objawy lub powikłania.12

Metody monitorowania glikemii

Istnieje kilka metod monitorowania poziomu glukozy we krwi:12

  • Glukometry – umożliwiają szybkie pomiary poziomu glukozy z kropli krwi
  • Ciągłe monitorowanie glukozy (CGM) – urządzenia, które mierzą poziom glukozy w płynie tkankowym co kilka minut
  • Badanie hemoglobiny glikowanej (HbA1c) – pokazuje średni poziom glukozy we krwi w ciągu ostatnich 2-3 miesięcy
  • Testy moczu na obecność ketonów – pomocne w wykrywaniu kwasicy ketonowej

Zalecane częstotliwości pomiarów

Częstotliwość monitorowania glikemii zależy od typu cukrzycy, stosowanego leczenia i indywidualnych potrzeb pacjenta. Ogólne zalecenia obejmują:12

  • Pomiar przed posiłkami i przed snem dla osób stosujących insulinę w wielu wstrzyknięciach dziennie lub pompę insulinową
  • Dodatkowe pomiary 1-2 godziny po posiłkach, zwłaszcza gdy wyniki przed posiłkami są w normie, ale HbA1c pozostaje podwyższone
  • Częstsze pomiary podczas choroby, stresu, zmian w aktywności fizycznej lub zmian w planie leczenia
  • Badanie HbA1c co 3 miesiące dla osób z cukrzycą

Rozpoznawanie wzorców hiperglikemii

Monitorowanie glikemii pomaga identyfikować wzorce hiperglikemii, które mogą wskazywać na potrzebę modyfikacji leczenia:12

  • Hiperglikemia na czczo (przed śniadaniem) – może wskazywać na niedostateczną dawkę insuliny bazalnej lub nocny efekt odbicia
  • Hiperglikemia po posiłkach – może wskazywać na nieodpowiednią dawkę insuliny posiłkowej lub niewłaściwą dietę
  • Hiperglikemia późno popołudniowa lub wieczorna – może być związana z działaniem hormonów lub niewystarczającą aktywnością fizyczną
  • Hiperglikemia występująca w określonych dniach tygodnia – może być związana z różnicami w aktywności lub diecie

Kiedy szukać pomocy medycznej

Ważne jest, aby wiedzieć, kiedy objawy hiperglikemii wymagają natychmiastowej pomocy medycznej:123

Należy skontaktować się z zespołem diabetologicznym lub udać się na oddział ratunkowy, jeśli występują następujące objawy:

  • Wymioty lub niemożność zatrzymania płynów
  • Splątanie lub senność
  • Duszność
  • Objawy odwodnienia
  • Poziom glukozy we krwi utrzymujący się powyżej 250-300 mg/dl pomimo podania insuliny
  • Pozytywny wynik testu na ketony w moczu
  • Ból brzucha i nudności
  • Owocowy zapach z ust

Jeśli poziom glukozy we krwi wynosi 240 mg/dl (13,3 mmol/l) lub więcej, należy użyć dostępnego bez recepty zestawu do badania ketonów w moczu. Jeśli test moczu jest pozytywny, organizm mógł rozpocząć zmiany, które mogą prowadzić do cukrzycowej kwasicy ketonowej. Należy skonsultować się z lekarzem na temat bezpiecznego obniżenia poziomu glukozy we krwi.1

Podsumowanie objawów hiperglikemii w cukrzycy

Rozpoznawanie objawów hiperglikemii jest kluczowe dla skutecznego zarządzania cukrzycą. Objawy mogą być różne w zależności od tego, jak wysoki jest poziom glukozy we krwi i jak długo utrzymuje się hiperglikemia.12

Nasilenie hiperglikemii Typowe objawy Kiedy szukać pomocy
Łagodna hiperglikemia – Zwiększone pragnienie
– Częste oddawanie moczu
– Zmęczenie
– Utrata wagi
Skontaktuj się z zespołem diabetologicznym, jeśli poziom glukozy we krwi jest regularnie powyżej 10 mmol/l (180 mg/dl)
Umiarkowana hiperglikemia – Niewyraźne widzenie
– Ekstremalne pragnienie
– Zawroty głowy
– Zaczerwieniona, gorąca, sucha skóra
– Niepokój, senność lub trudności z wybudzeniem
Skontaktuj się z lekarzem, jeśli objawy nie ustępują po zastosowaniu planu leczenia lub jeśli poziom glukozy we krwi utrzymuje się powyżej 13-14 mmol/l (240-250 mg/dl)
Ciężka hiperglikemia / kwasica ketonowa – Owocowy zapach z ust
– Nudności i wymioty
– Ból brzucha
– Duszność
– Szybki, głęboki oddech
– Splątanie
– Utrata przytomności
Natychmiast szukaj pomocy medycznej – to stan zagrażający życiu
Długotrwała hiperglikemia – Częste infekcje
– Wolno gojące się rany
– Problemy z widzeniem
– Drętwienie lub mrowienie w kończynach
– Problemy z nerkami
Regularne wizyty kontrolne z zespołem diabetologicznym dla monitorowania i zapobiegania powikłaniom

Zrozumienie objawów hiperglikemii i ich progresji może pomóc w szybkim rozpoznaniu problemów i podjęciu odpowiednich działań. Regularne monitorowanie poziomu glukozy we krwi, przestrzeganie zaleconego planu leczenia i utrzymywanie ścisłego kontaktu z zespołem diabetologicznym to najlepsze sposoby na zapobieganie poważnym powikłaniom związanym z hiperglikemią.12

    https://www.mayoclinic.org/diseases-conditions/hyperglycemia/symptoms-causes/syc-20373631
    High blood sugar, also called hyperglycemia, affects people who have diabetes. […] Hyperglycemia usually doesn’t cause symptoms until blood sugar (glucose) levels are high above 180 to 200 milligrams per deciliter (mg/dL), or 10 to 11.1 millimoles per liter (mmol/L). […] Symptoms of hyperglycemia develop slowly over several days or weeks. The longer blood sugar levels stay high, the more serious symptoms may become. But some people who’ve had type 2 diabetes for a long time may not show any symptoms despite high blood sugar levels. […] Recognizing early symptoms of hyperglycemia can help identify and treat it right away. Watch for: Frequent urination, Increased thirst, Blurred vision, Feeling weak or unusually tired. […] If hyperglycemia isn’t treated, it can cause toxic acids, called ketones, to build up in the blood and urine. This condition is called ketoacidosis. Symptoms include: Fruity-smelling breath, Dry mouth, Abdominal pain, Nausea and vomiting, Shortness of breath, Confusion, Loss of consciousness.

    Hyperglycemia or high blood sugar causes several symptoms, particularly if the condition persists in the long-term (chronic hyperglycemia). […] Most cases of acute or temporary hyperglycemia do not present with symptoms. Some of the symptoms associated with both acute and chronic hyperglycemia are described below, with the first three forming the classic hyperglycemic triad. […] Both polydipsia and polyuria occur when a high blood glucose level means glucose moves into the urine taking water, salt and minerals along with it. […] Other classic symptoms of hyperglycemia include the following: Blurred vision, Fatigue, Weight loss, Poor or delayed wound healing, Recurrent infections such as thrush or swimmers ear, Dry or itchy skin, Erectile dysfunction, Cardiac arrhythmia (irregular heart rate), Stupor, Seizures, Coma.

    Hyperglycemia occurs when the level of blood glucose gets too high. […] Hyperglycemia can affect people of any age and can cause a range of symptoms, including excessive thirst, hunger, fatigue, and/or an urge to urinate larger amounts than usual. […] Symptoms of hyperglycemia include: Urinating large amounts, Excessive thirst, Feeling tired, Frequent hunger, Dry mouth, Weight loss, Blurred vision, Recurrent infections (e.g., urinary infections, skin infections), Wounds (cuts, scrapes) that heal slowly. […] In people with type 2 diabetes, very high blood glucose levels can lead to a life-threatening condition called hyperosmolar hyperglycemic state (HHS), which causes profound dehydration and a change in mental status. […] In general, hyperglycemia that is transient does not cause long-term problems. But if hyperglycemia persists, it can lead to serious complications, including eye problems, kidney damage, nerve damage, and cardiovascular disease.
  • #1 Hyperglycemia in diabetes – Symptoms & causes – Mayo Clinic
    https://www.mayoclinic.org/diseases-conditions/hyperglycemia/symptoms-causes/syc-20373631
    In people who have diabetes, glucose tends to build up in the bloodstream. This condition is called hyperglycemia. It may reach dangerously high levels if it is not treated properly. Insulin and other drugs are used to lower blood sugar levels. […] Keeping blood sugar in a healthy range can help prevent many diabetes-related complications. Long-term complications of hyperglycemia that isn’t treated include: Cardiovascular disease, Nerve damage (neuropathy), Kidney damage (diabetic nephropathy) or kidney failure, Damage to the blood vessels of the retina (diabetic retinopathy) that could lead to blindness, Feet problems caused by damaged nerves or poor blood flow that can lead to serious skin infections, ulcerations and, in some severe cases, amputation. […] If blood sugar rises very high or if high blood sugar levels are not treated, it can lead to two serious conditions.
  • #1 Hyperglycemia (High Blood Sugar): Signs of an Episode
    https://www.verywellhealth.com/hyperglycemia-8604180
    Hyperglycemia is high blood glucose (sugar) levels. It is common in people with diabetes but can occur in people who have not been diagnosed with diabetes. It can develop slowly with no obvious symptoms. […] Depending on the cause of your hyperglycemia, you may not experience physical symptoms for months or years. This is because hyperglycemia can develop and progress slowly over time. […] Other times, as with type 1 diabetes for example, symptoms can develop a lot quicker in a matter of weeks. […] Symptoms of hyperglycemia may include: Increased thirst, Frequent urination, Increased hunger, Blurry vision, Tingling in the hands and feet, Unintentional weight loss, Fatigue, Sores or cuts that do not heal or that heal very slowly, Headache. […] Hyperglycemia often occurs in people with diabetes but can also occur in people without diabetes. Causes of hyperglycemia include insulin resistance, lack of insulin production, certain medications, stress, and some medical conditions.

    The symptoms of having high blood sugar can range from subtle to hard to ignore. Most people with hyperglycemia experience: Frequent peeing, Excessive thirst, Increased hunger, Blurred vision, Headache. […] If you have frequent episodes of high blood sugar, or you have untreated diabetes or prediabetes, you may notice some of the later consequences of chronic hyperglycemia, such as: Fatigue, Slow-healing cuts and sores, Skin infections, Vaginal yeast infections, Weight loss. […] Many people dont experience symptoms until their blood sugar is 250 mg/dL or higher. People with diabetes tend to notice the signs of hyperglycemia later than people without diabetes. […] Chronic hyperglycemia, meaning that your blood glucose levels are frequently above the normal, healthy range, can be bad for your health in the long run. Some of the problems caused by chronic hyperglycemia are: Diabetic ketoacidosis (DKA) or diabetic coma (a potentially life-threatening reaction to hyperglycemia, common in people with diabetes), Peripheral neuropathies, Poor wound healing/chronic wounds, Retinopathy (leading to vision problems), Coronary artery disease, Cerebral vascular disease, Chronic kidney disease. […] Hyperglycemia can be a serious problem if you don’t treat it, so it’s important to know whether your blood sugar levels are consistently high.

    High blood sugar (hyperglycemia) most often occurs in people who have diabetes that isn’t well controlled. The symptoms of high blood sugar can be mild, moderate, or severe. […] You may have mild symptoms if your blood sugar levels are consistently higher than your target range. Some people may not notice any symptoms when their blood sugar level is in this range. […] The main symptoms of mild high blood sugar are: Increased thirst. Increased urination. Weight loss. Fatigue. […] You may have moderate to severe symptoms if your blood sugar levels are consistently high. These symptoms include: Blurred vision. Extreme thirst. Light-headedness. Flushed, hot, dry skin. Restlessness, drowsiness, or difficulty waking up. […] People with type 1 diabetes and some people with type 2 diabetes produce little or no insulin. These people may also have: Rapid, deep breathing. A fast heart rate and a weak pulse. A strong, fruity breath odour. Loss of appetite, belly pain, and/or vomiting. […] If your blood sugar levels continue to rise, you may: Become confused and sluggish. Pass out (lose consciousness) if your blood sugar levels are very high.

    If hyperglycemia symptoms become too serious, you could form another life-threatening health problem called diabetes-related ketoacidosis (DKA). […] DKA tends to happen in people with diabetes who take insulin or those with type 1 diabetes but haven’t been diagnosed. […] You’re more likely to have hyperglycemia if you: Don’t take enough insulin or other diabetes medicines, Don’t inject insulin the right way or use expired insulin, Don’t stick with your diabetes food plan, Don’t stay active, Are sick or have an infection, Take medicines like steroids or those that keep your immune system in check, Are injured or have had surgery, Are stressed. […] If you have diabetes and notice any of the early signs of high blood sugar, test your blood sugar and call the doctor. […] If you work to keep your blood sugar under control follow your meal plan, exercise program, and medicine schedule you shouldn’t have to worry about hyperglycemia.

    The glucose level at which people with diabetes start to experience symptoms varies. Many people dont experience symptoms until their blood sugar is 250 mg/dL or higher. […] Its especially important to know the early signs of hyperglycemia and to monitor your blood sugar regularly if you take insulin or other medications for diabetes. If hyperglycemia is left untreated, it can develop into diabetes-related ketoacidosis (DKA), in which a lack of insulin and a high amount of ketones cause your blood to become acidic. DKA can also affect people who have undiagnosed Type 1 diabetes. This condition is an emergency situation that can lead to coma or death. […] Prolonged (chronic) hyperglycemia over the years can damage blood vessels and tissues in your body. This can lead to a variety of complications, including the following: Retinopathy, Nephropathy, Neuropathy, Gastroparesis, Heart disease, Stroke.

    Diabetes-related ketoacidosis (DKA): This complication mainly affects people with Type 1 diabetes or undiagnosed T1D. It happens when your body doesn’t have enough insulin. If your body doesn’t have insulin, it can’t use glucose for energy, so it breaks down fat instead. This process eventually releases substances called ketones, which turn your blood acidic. This causes labored breathing, vomiting and loss of consciousness. DKA requires immediate medical treatment. […] Blood glucose levels that remain high for too long can damage your body’s tissues and organs. This is mainly due to damage to your blood vessels and nerves, which support your body’s tissues.
