Diet: Eating high fat, high calorie foods causes weight gain.Lack of exercise: Sedentary people don't burn as many calories as active people.Genetics: Your genes may influence how much fat your body stores and where it is stored. But genes alone do not mean you will be obese.Age: People gain weight as they get older, because they tend to be less active and to lose muscle mass.Psychological issues: Some people overeat when they are upset or stressed.Medications: Some drugs, such as corticosteroids, blood pressure medication, and tricyclic antidepressants, can cause you to gain weight.Medical problems: Rarely, obesity is due to a medical problem such as Cushing syndrome (where the adrenal glands produce too much hormone) or hypothyroidism (where the thyroid gland doesn't produce enough hormone). Conditions such as osteoarthritis cause people to be less active, which can lead to weight gain.Prenatal environmental factors: Several studies show that adult men and women who were born small for their gestational age are more likely to be overweight or obese than those who were of normal size at birth. Maternal smoking and excess weight gain is also associated with offspring obesity.
