Hello varsha;
welcome to HealthcareMagic
If you have increase in weight like a kilo then probably this is not because of retention of water and you may be having problem with your
thyroid.Increase in weight;tiredness;hair fall;
depression are few symptoms of hypothyroid.So please get the thyroid test T3;T4;
TSH done and if that is normal then you can get treated for water retention and if the thyroid is a problem then you have to get treated for that.
Thanks
