Here’s what else it could mean….
If you have a small, tickling cough, the culprit may be your blood pressure medication. For about 1 in 5 patients, a little known side-effect to those drugs is a dry, nagging cough. So ask your doctor about switching to a different type of blood pressure medication. Otherwise, ask him about adding some iron to your diet. Research shows that taking a daily iron supplement can calm a drug-related cough in as little as one month.
Also, a persistent cough could be a sign of acid reflux. Experts say about 3 out of 4 people who experience heartburn after eating also develop a cough! The #1 way to ward off acid reflux is to eat lighter meals. Otherwise, try sitting upright for at least 2 hours after a meal. Then sleep on your left side. That way, acid passes more quickly from your stomach into your intestines.
