Does Tenormin Cause Weight Gain?

Yes. Weight gain can occur as a side effect of some beta blockers. The average weight gain is about 2.6 pounds (1.2 kilograms). Weight gain is more likely with older beta blockers, such as atenolol (Tenormin) and metoprolol (Lopressor, Toprol-XL).

Can you lose weight while on beta blockers?

And in a separate look at 30 patients with high blood pressure, they found that people on beta-blockers generally burned fewer calories and fat after a meal -- measured by a device called a calorimeter. The patients on beta blockers also reported lower physical activity levels in their day-to-day lives.

Does atenolol cause fluid retention?

Some beta blockers, particularly older medications such as metoprolol and atenolol, can contribute to weight gain. While there's no consensus on why this happens, it's believed to be linked to fluid retention or the medication's effects on your metabolism.
