Hi.
I've gone through your query. I can understand your 
anxiety. 
For obesity you have to rule out underlying pathology if any. I advice you to, 
- Do thyroid function test to rule out 
hypothyroidism. 
- Do USG pelvis to rule out 
PCOD. 
- Maintain proper diet. Do not have milk products, eat excess of green leafy vegetables, fruits, salads etc. 
- water intake 1glass / hr/ day. 
- regular exercise & 
YOGA. 
- Appetite suppressants once a day or tab. 
Orlistat with each meal three times a day 
- surgery is the final option 
Hope I have answered your query. Let me know if I can assist you further. Take care. 
Regards, 
Dr. Yogapriya V, General and family physician.
