Is there a homeopathic treatment for over weight?

No if the weight gain is not secondary to a disease. You will have to control your diet. Calorie input and output equation has to be balanced. Excess of calories has to be burnt by regular exercise. You might have came across many weight reduction centers using medications, however, confirm with the doctor involved with the center if he / she will reduce excess of weight permanently by means of medications only. If at all with medicines, the medication will act only until you are taking them. Once you stop taking the medicines you will regain back your weight.
