Certain prescription drugs used to treat mood disorders, seizures, migraines, diabetes and even high blood pressure can cause weight gain. Dr Lynn Teo from the Dermatology Practice confirms that certain types of medication can impede weight loss. She explains, “Some types of medication increases appetite, water retention and even the production of gastric juices in the stomach, making one hungrier. For example, certain types of antidepressants may increase one’s appetite. If one is on oral steroids, one may experience side effects such as gastritis and even hunger which will prompt a higher intake of calories.” She adds, “Check with your doctor if any of the medication that you are on can interfere with your attempt to lose weight. And never attempt to stop or reduce your medication without consulting with your doctor.”
