Most of the time, medicines make you feel better. But some can upset your stomach or cause other trouble with your digestive system. If you have issues like this, talk with your doctor. She might suggest something else or suggest you change your dose.
Aspirin can affect the lining of your stomach and cause belly pain and other problems. Other pain relievers, like ibuprofen and naproxen, can lead to heartburn, irritation, and other stomach trouble, too. If that happens, you might try taking these with food or with a drug that treats heartburn.
A mix of bacteria helps your body break down food you eat and turn it into energy. Antibiotics can kill the “good” bacteria in your body, along with the “bad,” and upset the healthy balance that makes your digestive system work like it should.
Foods that have “good” bacteria known as probiotics -- like yogurt that says “active and live cultures” on the label -- may help keep things in check. And be sure to follow any directions your doctor gives you about taking them on an empty or full stomach.
If your blood has high levels of cholesterol, which can cause heart problems, your doctor might recommend medicine to bring those down. Some of those can affect your digestion and cause problems like gas, constipation, or diarrhea.
Most over-the-counter laxatives don’t help with this, but your doctor may be able to give you something that will.
Nausea, vomiting, and diarrhea are among the most common side effects of the powerful drugs used to treat cancer. Your doctor can give you medicine to ease those effects. Changes to what you eat -- like staying away from fried or spicy foods -- can help, too.
