Hello dear, The symptoms as mentioned in your post can be attributed to hormonal imbalance due to Thyroid problem. Kindly get a Thyroid profile done & consult an Endocrinologist. It is not advisable to take any medication or diet pills for losing weight, because: 1. The medications interfere with the normal metabolic rate of the body & causes a number of side effects 2. The individual tends to gain more weight after stoppage of the medication. For effective weight control, equal importance should be given to both diet & exercise. So, a low calorie low fat diet and regular exercise should be followed such as: 1. Avoid eating white breads, rice and pasta. They have high calories and increases the blood sugar level. 2. It is better to have complex carbohydrates such as whole wheat bread, oatmeal and brown rice. 3. Consume low fat versions of milk and cheese and avoid oily foods. 4. Have a diet rich in low calorie protein foods such as egg whites, skinless chicken, fish, etc. 5. It is better to avoid soft drinks and fruit juices which are rich in calories. Instead, drink large amount of water (about 6 to 8 glasses) throughout the day. 6. Dietary fiber such as whole grains, vegetables, fruits, and nuts can also be included in the diet. Wishing you a Good Health. Take care.
