Unintentional weight gain can have many causes. Metabolism slows down as you age. This can cause weight gain if you eat too much, eat the wrong foods, or do not get enough exercise.
Drugs that can cause weight gain include:
- Birth control pills
- Corticosteroids
- Some drugs used to treat bipolar disorder, schizophrenia, and depression
- Some drugs used to treat diabetes
Hormone changes or medical problems can also cause unintentional weight gain. This may be due to:
- Cushing syndrome
- Underactive thyroid, or low thyroid (Hypothyroidism)
- Polycystic ovary syndrome
- Menopause
- Insulin Resistance
- Metabolic Syndrome
