Metabolism is characterized by the rate your body normally converts food calories into energy. Factors such as your body size and physical activity level influence metabolism. According to MayoClinic.com, other conditions that may slow metabolism include the aging process, genetic disorders and thyroid problems. If you are concerned about your decreasing metabolism, talk to your physician about potential remedies and causes.
The Aging Process
As humans age, their normal metabolic rate decreases. According to MayoClinic.com, age-related metabolism reduction often occurs because of muscle tissue deterioration. To increase your metabolic rate or prevent metabolism reduction as you age, add strength-training repetitions into your regular exercise regimen. Examples of strength-training activities include dips, push-ups, sit-ups, squats, lunges and the use of weight machines or dumbbells, pilates or yoga. For optimal results, seek guidance from a certified fitness instructor who can professionally structure individualized programs for your particular concerns.
Hypothyroidism
Hypothyroidism, commonly referred to as underactive thyroid, normally occurs when the thyroid gland fails to produce hormones that positively affect your metabolism. If left untreated, it causes your metabolism to decrease. Although hypothyroidism can occur at any age, it primarily affects women in their 50s, reports MayoClinic.com. Additional symptoms of hypothyroidism include constipation, unexplained weight gain, muscle weakness, depression and puffy face. Physicians often treat hypothyroidism through synthetic thyroid supplementation or other alternative methods. Weight gain and other symptoms normally subside once the condition is managed. A nutrient-rich diet and regular physical activity also contributes to improving your metabolism and hypothyroidism.
Prader-Willi Syndrome
Prader-Willi syndrome is an uncommon genetic disorder that produces slow metabolism, insatiable appetite and delayed development in children and infants. The New York University Langone Medical Center states that Prader-Willi syndrome is naturally caused by genetic defects that are derived from the paternal parent. As children with PWS develop, they typically maintain excessive amounts of body fat and short statures. Although PWS symptoms vary, all patients suffer from excessive hunger and reduced metabolism, a potentially unhealthy combination. Treatment of the disorder normally involves low-calorie diets and frequent physical activity under adult supervision. Discuss genetic testing with your physician if you suspect your child suffers from Prader-Willi syndrome.
Medications
If you are diagnosed with an illness such as arthritis, lupus, depression or post traumatic stress disorder, your metabolism may decrease when put on certain medications, reports Drugs.com. Prednisone, used to combat types of allergic reactions, can slow your metabolism and cause weight gain. Zoloft, Celexa, Paxil and other serotonin reuptake inhibitors can adversely affect your body's metabolism and cause weight gain. Selective serotonin reuptake inhibitors (SSRIs) affect chemical levels in the brain and influence how your body functions. Metabolism, moods and sleep patterns can all be adversely affected. Changes in exercise and diet may help to control your weight while taking these types of medications.
