Yes, because the kidneys try to flush out excess sugar through urine, which dehydrates the body. Be very careful with sweet juices or energy drinks to cure thirst, only drink plain water.

Definitely. When my sugar was high, I was visiting the bathroom every half hour and my mouth felt like a desert. Once I got my insulin levels right, the constant thirst and dehydration stopped.

Yes, frequent urination in diabetes causes rapid dehydration. The most practical tip is to keep a water bottle next to you always and sip water throughout the day, while keeping a check on your HbA1c.

Absolutely, severe thirst is a classic diabetic symptom. Your body is losing fluids rapidly to get rid of glucose. Drinking water is good, but you must bring your sugar down to fix it permanently.

According to my diabetologist, osmotic diuresis occurs when blood sugar exceeds 180, leading to heavy fluid loss and severe dehydration. It is crucial to monitor electrolytes during such phases.
