If you’ve been experiencing frequent heartburn or discomfort after meals, you may be dealing with acid reflux or a more serious condition known as GERD (gastroesophageal reflux disease). Gastrointestinal (GI) issues are common among people living with chronic kidney disease (CKD), often due to medication side effects, dietary restrictions, or the disease itself. While treatment usually begins with lifestyle changes, some people need medications like proton pump inhibitors (PPIs). If you have CKD or kidney failure, it’s crucial to understand how PPIs work—and how they may impact your kidney health.*

GI Symptoms and Triggers

Your stomach naturally produces acid to digest food and fight bacteria. But when acid backs up into your esophagus, it can lead to symptoms such as: 

• Chest burning, 
• Regurgitation,  
• Hiccups,
• Coughing, and 
• Pain.  

While occasional acid reflux is common, symptoms that occur more than once a week may indicate GERD.

You can often ease symptoms by avoiding triggers like:

• Caffeine, 
• Alcohol,  
• Chocolate,   
• Spicy or greasy foods, and 
• Eating close to bedtime. 

Elevating your head while sleeping, quitting smoking, and managing your weight can also help. But if these strategies don’t offer relief, your healthcare provider might recommend PPIs to reduce acid production in your stomach.

What to Know About PPIs and Kidney Health

PPIs are effective medications for reducing stomach acid, but they come with risks—especially for your kidneys. Studies suggest a potential link between long-term PPI use and chronic kidney disease, though the evidence isn’t definitive. What’s more certain is that PPIs can cause acute interstitial nephritis, an allergic reaction that causes kidney inflammation. Left untreated, this can lead to serious kidney damage.

If you already have kidney disease or are on dialysis, the use of PPIs may need to be limited. PPIs can also interfere with your body’s ability to absorb magnesium and iron—two minerals that are often already low in people with CKD. This increases your risk for:

• Bone fractures, 
• Anemia, and 
• Other complications.

Despite these risks, your doctor may still prescribe a PPI if the benefits—such as preventing gastrointestinal bleeding or managing severe reflux—outweigh the potential harm. The key is using the lowest effective dose for the shortest possible time under close supervision.

Making Informed Choices with Your Provider

While PPIs are generally safe for short-term use, you should never self-treat with over-the-counter acid reducers if you have kidney disease. Always consult your healthcare provider to weigh the benefits and risks of PPIs and explore alternatives like H2 blockers. By staying informed and involved in your treatment, you can protect your digestive health without compromising your kidneys.
