Weight gain - unintentional
Definition Unintentional weight gain is an increase in body weight that occurs when a person takes in more calories than the body needs or uses, causing increased fat storage.
Considerations Almost 40% of all Americans are overweight. As we age, our metabolism slows, which can cause weight gain unless we also reduce food intake and get adequate exercise.
Weight gain can also be a significant symptom of several endocrine diseases such as Cushing's syndrome or hypothyroidism. It may also be caused by heart or lung disorders as well.
A progressive weight gain occurs with pregnancy, whereas a periodic weight gain may occur with menstruation. A rapid weight gain may indicate dangerous fluid retention.
Common Causes
- Overeating and lack of exercise
- Poor eating habits (high-carbohydrate, high-calorie diet)
- Emotional factors such as guilt, depression, and anxiety
- Slower metabolism, which is normal with aging
- Smoking cessation
-
Alcohol consumption
-
Primary hypothyroidism
- Endocrine disorders including Cushing's syndrome or polycystic ovary syndrome
- Drugs such as corticosteroids, cyproheptadine, lithium, tranquilizers, phenothiazines, and tricyclic antidepressants
- Medications that increase fluid retention and cause edema (abnormal pooling of fluids in the tissues)
Home Care Take action by starting a proper diet and exercise program. Counseling or psychological aid may be helpful.
Set realistic weight goals to maintain a healthy weight. Consult with a health care provider about specific measures.

Weight gain caused by emotional problems may require psychological counseling. Talk to your provider about an appropriate diet and exercise program and realistic weight loss goals. If weight gain is caused by a physical illness, treatment (if there is any) for the underlying cause will be prescribed.
If weight continues to be a problem despite diet and exercise, talk with your health care provider about other treatment options, including medications and surgery.
