Hello
Hypothyroidism can not be cured by any pathy.
You have less production of thyroxine hormones by your thyroid ,hence you have to take it daily.
As far as weight loss is concerned,by taking plenty of water and doing only yoga will not help.
You must do two things for that
1... Consume less calories
2... Burn more calories by doing aerobics or brisk walking or running daily.In yoga you are burning much calories,hence you are not getting the required results.
3... Continue yoga along with your exercises.
Thanks

1. Alternative to hormone is not available in any -pathy, so continue with Thyroxine.
2. please mention about your age,because as one goes older, drug generally move slowly in them, which might be the cause in you?
3. are you taking your medications regularly and at the same time?
4. finding the best dose is a matter of hit and trial, your health care provider may come up with the correct and proper dosage.
5. where are you keeping the medications, as keeping them in areas of heat and moisture (bathroom,direct sunlight,car,dishwasher) will result in reduction of their efficacy and Levothyroxine is one of them.
6. avoid ghee,butter,cheese,cream, deep fried foods, sweet potatoes,beet,nuts, bananas,mango, chickoos,grapes,chocolates,cakes,pastries,ice-creams,jams,processed and tinned foods.
