Can Gaviscon Make You Constipated?

Gaviscon is a widely used over-the-counter medication for heartburn and indigestion. It alleviates symptoms of acid reflux, such as the burning sensation and upset stomach caused by stomach acid flowing back into the esophagus. Available in liquids and chewable tablets, Gaviscon offers quick symptom management.

How Gaviscon Provides Relief

Gaviscon works through a unique dual-action mechanism to combat acid reflux. Its main active component, sodium alginate from brown seaweed, forms a thick, viscous layer or “raft” when it contacts stomach acid. This protective barrier floats on stomach contents, physically obstructing acid from rising into the esophagus and causing irritation.

Many Gaviscon formulations also contain antacids like calcium carbonate, sodium bicarbonate, or a combination of aluminum hydroxide and magnesium carbonate. These antacid ingredients neutralize excess stomach acid, reducing discomfort. The combined action of the alginate barrier and acid neutralization provides rapid relief from heartburn and indigestion symptoms. This protective layer can remain effective for several hours, offering sustained relief.

Gaviscon and the Risk of Constipation

While Gaviscon effectively manages acid reflux symptoms, some ingredients can contribute to constipation. This side effect is primarily linked to its antacid components, specifically calcium carbonate and aluminum hydroxide, found in various Gaviscon formulations. These compounds can influence bowel movements differently than the primary alginate action.

Calcium carbonate, a common antacid in some Gaviscon products, is known to have a constipating effect. When ingested, it neutralizes stomach acid and can bind with fats and bile acids in the digestive tract. This process reduces water content in stool and slows waste movement, leading to harder, drier stools and decreased bowel frequency.

Similarly, aluminum hydroxide, another antacid in some liquid Gaviscon formulations, also tends to cause constipation. Aluminum acts as an astringent, slowing intestinal motility, and can bind to phosphate in the gut. Its constipating effects are why it is often combined with magnesium-containing antacids, which typically have a laxative effect. Individual susceptibility, dosage, and duration of Gaviscon use can all influence the likelihood and severity of this side effect.

What to Do About Gaviscon-Related Constipation

If you experience constipation while taking Gaviscon, several strategies can help manage this side effect. Increasing your daily fluid intake is important, as proper hydration helps soften stools and promote easier passage. Incorporating more dietary fiber into your diet is also beneficial; fiber adds bulk to stool and stimulates bowel movements. Good sources include fruits, vegetables, whole grains, and legumes.

Engaging in regular physical activity can further support healthy bowel function. Even moderate exercise, such as daily walking, can help stimulate intestinal contractions and encourage regular bowel movements. If these lifestyle adjustments do not provide sufficient relief, consider consulting a healthcare professional. They can review your Gaviscon dosage and determine if an alternative formulation might be more suitable. Some Gaviscon products contain magnesium, which can have a mild laxative effect and may help counteract constipation.

It is important to seek medical advice if constipation becomes severe, lasts for an extended period, or is accompanied by other concerning symptoms like abdominal pain, bloating, or blood in the stool. A doctor can assess the situation, rule out other potential causes of constipation, and recommend appropriate interventions or alternative treatments for your acid reflux. Always follow the instructions on the product label and consult a healthcare provider if you have questions or experience persistent side effects.
