From Live Science:
This Week's Question: I've been very thirsty lately and someone mentioned to me that this
is a symptom for diabetes. Is that true?
An intense thirst is one diabetes symptom. Here are others: frequent urination, strong hunger, fatigue, unintended weight loss, slow-healing sores, dry and itchy skin, numbness or tingling in your feet, and blurred vision. However, some people with diabetes do not have symptoms.
Diabetes mellitus is a group of diseases characterized by high levels of blood sugar. Diabetes can create serious health problems, but diabetics can control the disease.
