Atenolol, which is sold under the brand name Tenormin, belongs to a class of medications called beta blockers. It is mainly prescribed to treat high blood pressure, according to Drugs.com. Atenolol is also used to treat or prevent angina and heart attack. The drug works by dilating blood vessels and slowing heart rate, which lowers high blood pressure and improves blood flow. Atenolol may affect your metabolism.
Slow Metabolism
Metabolism is the process by which your body converts proteins, carbohydrates and fats into energy that is used for important body processes. Atenolol may slow your metabolism, which can lead to excess weight gain, according to MayoClinic.com. If the weight gain continues to bother you, your doctor may switch you to newer beta blockers that do not cause weight gain as a side effect. If you are taking beta blockers for heart failure, contact your doctor if you experience sudden weight gain.
Speed Metabolism
During Atenolol therapy, you can prevent excess weight gain by engaging in more physical activities. Regular physical activity helps speed your metabolism and causes your body to burn more calories. Try to exercise for at least 30 minutes every day. Avoid vigorous activities if you have heart disease. Walking is a less strenuous activity for people with heart problems. Consult your doctor before you engage in any new form of physical activity.
Diet
A low-fat diet can help prevent excess weight gain caused by atenolol. Avoid fatty foods, such as whole milk, whole eggs, fried vegetables, creamy soups, avocados, cream, cheese, bacon, hot dogs, baked goods, sausages, ground beef, spared ribs and pork. Eat a low-fat diet that contains plenty of whole grains, fruits and vegetables. Drink six to eight glasses of water every day. A low-sodium diet is also recommended when you are taking Atenolol, according to PubMed Health. Sodium causes water retention, which can lead to weight gain. Avoid high-sodium foods such as cured meat and canned food.
Effects
When taking Atenolol, you may experience common side effects, such as dizziness, lightheadedness, drowsiness, fatigue, weakness, insomnia, anxiety, depression, decreased sex drive, nausea, vomiting and diarrhea, according to Drugs.com. Seek immediate medical attention if you experience shortness of breath, problems breathing, wheezing, fainting, hives, or swelling of the face, tongue and throat.
