Sertraline is a selective serotonin reuptake inhibitor (SSRI) that is used in the treatment of common mental illnesses such as depression, obsessive-compulsive disorder, premenstrual dysphoric disorder and panic attacks. It works by blocking the reuptake of serotonin in the brain, resulting in a loss of depressive symptoms. There is a connection between sertraline and weight gain, and weight changes are listed as one of the drug's side effects. The connection between sertraline and weight gain is a significant concern for patients who are taking this medication.
SSRIs originally were prescribed to assist with weight loss in obese people. Studies have shown that the prolonged use of SSRIs can contribute to weight gain, causing symptoms similar to hypoglycemia including hunger, dizziness and headaches. The exact mechanism behind this is not known, but it generally is believed that SSRIs increase the patient's cravings for carbohydrates and reduce the body's sensitivity to insulin, causing weight gain. Insulin resistance causes weight gain around the midsection and lowers the body's metabolism. The instructions distributed with sertraline recommend that patients should discuss all side effects, including weight gain, with their doctors if the side effects do not diminish with time.
Sertraline typically is first prescribed at 50 milligrams once per day. This dosage might be increased by 50 milligrams after a week until reaching a maximum of 200 milligrams per day. The connection between sertraline and weight gain increases as the dosage increases.
Weight gain usually is considered a serious side effect of sertraline. Studies have shown an average weight gain of 15-20 pounds (6.8-9.1 kg) in patients who are taking sertraline. Weight gain can cause poor self-image, health issues and depression, which is counterproductive when taking an anti-depressant. The purpose of an anti-depressant is to lessen the patient's depressive moods. The connection between sertraline and weight gain might derail those efforts.
There are several ways that one can limit the weight gained while taking sertraline. Sertraline increases the patient's carbohydrate cravings, so he or she should limit the intake of high-calorie foods and sweets. A diet and exercise regimen that minimizing caloric intake and helps burn calories can help counteract any weight gained while on sertraline. Exercise also improves a person's depressive tendencies by making him or her feel better and healthier.
The connection between sertraline and weight gain is not the only side effect for this medication. Sertraline prescribed for mood disorders includes other side effects such as drowsiness, dizziness, sleep problems and decreased sex drive. These side effects are reduced as time passes. Any patient who experiences rigid muscles, nausea, headache, trouble concentrating or hallucinations while taking sertraline should seek immediate medical attention.
