Peptic ulcers are sores that form in the lining of your stomach or in the first part of the intestine called the duodenum. They are usually caused by Helicobacter pylori (H. pylori) or non-steroidal anti-inflammatory drugs (NSAIDs) and can be aggravated by stress, medications, and food.

These sores are easy to diagnose, but can get worse without treatment. This article will explore the common symptoms of stomach ulcers, why they might feel worse at night, and how your sleep position can relieve ulcer-related pain.

Sleep is crucial to maintaining gastrointestinal tract health. Stomach ulcers can affect sleep quality, and poor sleep can make ulcers worse or cause them to return.

One study found that people who slept nine or more hours each night had lower rates of stomach ulcers than those who slept seven hours. This suggests that sleep can have a protective effect against stomach ulcers.

Stomach ulcers can disturb sleep for several reasons, and making a few simple changes may help to improve sleep quality and accelerate healing.

Sleep habits can affect digestive system disorders like ulcers and gastroesophageal reflux disease (GERD), two conditions that are often confused with one another. Making changes to your sleep habits can help ease symptoms of both.

Increased stomach acids from stress, spicy foods, and medications can exacerbate symptoms of GERD and peptic ulcers. These acids build up the most after eating, so if you eat late at night, discomfort can worsen when you sleep. Avoiding late-night snacks or meals may help ease symptoms.

Changing your sleep position and sleeping upright uses gravity to help control the movement of stomach acids and may bring some relief.

If discomfort is caused partly by GERD, lying on your left side can help move your stomach contents more quickly into the rest of your digestive tract.

Additional research is needed to find the best sleep position for people prone to stomach ulcers.

Your first instinct to manage the pain of a stomach ulcer may be to reach for an over-the-counter (OTC) pain reliever but using NSAIDs is one of the leading causes of stomach ulcers. If you have a history of peptic ulcers or are at risk of developing an ulcer, talk to your healthcare provider about your NSAID use and consider alternative ways to manage your pain.

Your healthcare provider can prescribe antibiotics if you have an ulcer caused by the H. pylori bacteria. Other medications to reduce stomach ulcer pain focus on reducing stomach acid or protecting your stomach lining, such as:

Medications like Pepcid and Prilosec can be purchased OTC, but others (Protonix) are only available with a prescription from a healthcare provider. Some people need a combination of medications and lifestyle changes to find relief.

Historically, it was felt that spicy or acidic foods could cause stomach ulcers, but evidence points to H. pylori and NSAID use as the primary causes.

This doesn't mean that diet does not affect symptoms or how ulcers progress. Eating triggers the production of stomach acids. Consuming a big meal or certain foods can increase the acid in your stomach and aggravate an ulcer. This may be especially true at night due to the positioning of the stomach and the movement of acids.

Alcohol and caffeine contribute to stomach ulcer pain and poor sleep quality. Avoiding certain foods that trigger ulcer pain and limiting eating before bed can help relieve ulcer pain and improve sleep.

You can also try to improve your sleep with better sleep hygiene, which can begin with eliminating distractions. The Centers for Disease Control and Prevention (CDC) recommends taking the following steps to get better sleep.

The stomach and digestive tract are lined with delicate mucus membranes. Once damaged, this tissue can be easily aggravated, causing pain and other symptoms. A healthcare provider can diagnose the cause of your pain by asking about symptoms like:

More severe ulcers may cause:

NSAID use and H. pylori infections are the most common causes of stomach ulcers, but there are risk factors that can increase your chances of developing these injuries. These risk factors damage or weaken your stomach lining and make your tissues more vulnerable to ulcer development. Risk factors include:

In most cases, ulcers will heal with treatment. If left untreated, they could get worse and lead to complications like:

Schedule an appointment with your healthcare provider if you think you have a stomach ulcer.

If you develop any of the following symptoms, seek immediate medical treatment:

Stomach ulcers affect more than 4 million Americans yearly, and 1 in 10 people will develop one in their lifetime. Ulcers aren't rare. Still, they can lead to serious complications if left untreated. Good sleep is an important preventive tool. Talk to your healthcare provider about the best treatment for a stomach ulcer.

Stomach ulcers are small wounds that can develop in your digestive tract. Bacteria and medications can cause ulcers, and poor sleep habits can contribute to symptoms. Ulcer pain can wake you up at night and cause problems with your sleep, so getting a good night's rest is important for preventing and managing peptic ulcers. Your healthcare provider can help you find the right combination of medications and lifestyle changes to treat stomach ulcers and improve sleep.

Stomach ulcers will eventually heal, usually only after medication and lifestyle changes. Untreated ulcers can lead to more serious complications like bleeding.

Some people may be awakened by stomach ulcer pain at night, especially with certain sleep and eating habits. Stomach acids don't cause ulcers, but they can irritate them. Avoiding late night snacking and sleeping with your head elevated can help.
