A Simple Part of Life
Some weight gain is a normal part of life, particularly for women. Weight gain occurs with pregnancy, and a periodic weight gain may occur with menstruation (typically referred to as "water weight"). Rapid weight gain that can't be attributed to either of these normal causes may be a sign of dangerous fluid retention, and anyone experiencing it should notify their doctor.Aging is also a natural and expected cause of a certain amount of weight gain. As we age, our metabolism slows, which can cause weight gain unless we also reduce the amount of food we eat and get adequate exercise.
Something More
You may also gain weight because of other reasons that are not a part of everyone's daily life:- significant alcohol use
- use of certain drugs such as corticosteroids, cyproheptadine, lithium, tranquilizers, phenothiazines, some antidepressants, and medicines that increase fluid retention and cause edema
- emotional factors, such as guilt and anxiety
- quitting smoking
Underlying Medical Concerns
The extra pounds you add on may be what seems most concerning in your mind, but there are cases where the worry truly is something greater. Weight gain can also be a symptom or the result of certain medical conditions. These can include:- endocrine diseases, such as Cushing syndrome and hypothyroidism
- heart disorders
- lung disorders
- polycystic ovary syndrome (PCOS)
- depression
- constipation
- hair loss
- sensitivity to cold
- swollen feet and shortness of breath
- uncontrollable hunger accompanied by palpitations, tremor, and sweating
- vision changes
