Hi,
As you have mentioned your symptoms get relived after drinking fluids, these are most likely due to
dehydration (lack of water).
You also mentioned there is strong diabetes history on maternal side, that make you prone for diabetes.
Following things also make person prone for diabetes-
1) Over weight. (BMI >25)
2) Sedentary life style, lack of exercise.
3) Family history of diabetes (as in your case)
I would like to advise you
1) Drink adequate fluids.
2) Daily exercise (at least 150min/week)
3) Regularise your meal plan.
4) Yearly
screening for diabetes by doing OGTT/
HbA1c.
5) Watch for symptoms of diabetes like
weight loss, increased thirst, increased frequency of urination, increased hunger.
