Why do diabetics drink so much water?

It's due to high blood glucose. When blood sugar levels are elevated, the kidneys try to filter out excess glucose, which draws more water from the body. This increased urination (polyuria) leads to dehydration and intense thirst (polydipsia), causing them to drink a lot of water.

This is a classic symptom of uncontrolled diabetes, actually. When there's too much sugar in the blood, the kidneys work overtime to filter it out. To do this, they pull more water from your body, making you pee a lot and feel constantly thirsty. It's the body's way of trying to flush out the excess sugar.

Yaar, actually, when blood sugar is high, the body tries to get rid of it through pee, right? So the kidneys pull a lot of water out to dilute that sugar. That makes you feel super thirsty all the time. It's a cycle. Polydipsia bolte hain isko.

Oh, so it's because of the high sugar? Like the body is trying to dilute it or something? Does it mean they are always dehydrated even if they drink a lot? I'm trying to understand this better.

Haan na, this is a very clear sign. When their blood sugar is too high, their kidneys try to flush out all that extra sugar through urine. To do that, they need a lot of water. So, they feel constantly thirsty and end up drinking more, and then peeing more. It's a cycle to remove the sugar.
