There are diabetes symptoms which are general in nature. Even though there are several forms of diabetes they tend to have similar symptoms when untreated. These are excessive thirst (polydipsia) and excessive urine production (polyuria).
Diabetes types also typically differ in the time of their onset to the time at which symptoms are noticed.
Time of onset of symptoms may be abrupt or occur gradually over years and even decades. The severity of symptoms will also vary from individual to individual.
Hopefully symptoms then eventually lead to the point of diagnosis when the patient presents to a medical professional and is tested.
Diabetes is dangerous due to the related complications that arise due to the disease. These complications include cardiovascular damage and effects (i.e. stroke, heart attack), susceptibility to infections, blindness, kidney damage, and nerve damage.
If untreated or poorly controlled the disease can be fatal.
Diagnosis is dependent on medical testing and treatment includes a combination of diet, exercise, and for most individuals, drug treatment.
The general diabetes symptom of excessive thirst and urination should diminish with proper treatment.
The different diabetes types are covered below where more specific symptoms can be addressed.
