yes. you need to check your HgA1C to see if you have diabetes.
also, have your thyroid checked too.
I don't know what your health care is like in India, but I would ask a doctor to test you for diabetes and a general health test. An increase in thirst can indicate diabetes and losing weight can be a sign too. Diabetes won't just go away, so try and see a doctor. If only to give you peace of mind that you are ok!
it's not like i am thirsty always..... but i finish up with an empty bottle every time i sip it... it makes my stomach full.....
Are you actually thirsty? Have you been checked for diabetes?
