Hello Thyroid normal , cholesterol normal ,blood sugar normal . Weight is increasing , height is 4,9 . You din t mention your menstrual history as this is important because in spite of this that you are not having kids ( married for 3 years ) . The most common cause of gaining weight ( if you are taking low calories diet ) may be Poly Cystic Ovarian Disease ( POCD) . Diagnosis can be confirmed by ultrasound of both ovaries . 2nd reason of such weight gain may be due to high calories diet and consumption of calories very low ( if any ). Hormonal imbalance is another common cause , diagnosis can be confirmed by examination by an ENDOCRINOLOGIST . So deal as mentioned above. Good luck.
