Do kidney stones cause constipation


Kidney stones are a painful and common urological condition that affects millions of people worldwide. They are solid deposits made up of minerals and salts that form in the kidneys and can cause excruciating pain when they travel through the urinary tract. While kidney stones are primarily associated with urinary symptoms, some individuals wonder if they can also cause constipation. In this article, we will explore the relationship between kidney stones and constipation and whether there is a link between the two.

Understanding Kidney Stones

Kidney stones, or renal calculi, typically form when certain minerals and salts accumulate and crystallize in the kidneys. These stones can vary in size, from as small as a grain of sand to as large as a golf ball. They often cause intense pain when they move through the urinary tract and block the flow of urine. Common symptoms of kidney stones include severe back or abdominal pain, pain during urination, frequent urination, and blood in the urine.

Kidney Stones and Constipation: Is There a Connection?

While kidney stones are primarily associated with urinary symptoms, they are not known to directly cause constipation. Kidney stones and constipation are two distinct medical conditions with different causes and symptoms.

Constipation, on the other hand, is a gastrointestinal issue characterized by infrequent or difficult bowel movements. It is usually caused by factors such as dehydration, a low-fiber diet, lack of physical activity, certain medications, or underlying medical conditions. Symptoms of constipation may include abdominal discomfort, straining during bowel movements, and infrequent stools.

However, it’s important to note that in some cases, kidney stones and constipation may coexist. If you experience both conditions simultaneously, it could be due to unrelated factors. For example, pain from kidney stones may make you less active, leading to reduced physical activity and slowing of the digestive system, which can exacerbate constipation. Additionally, some medications used to manage kidney stone-related pain may have constipation as a side effect.

Kidney Stones and Other Gastrointestinal Symptoms

Although kidney stones themselves don’t typically cause constipation, they can lead to various gastrointestinal symptoms. These symptoms may include nausea and vomiting, which can sometimes be associated with pain from kidney stones. These symptoms, however, are generally secondary to the primary issue of kidney stones rather than a direct cause of constipation.

Management and Prevention

If you are dealing with kidney stones and are concerned about constipation or other gastrointestinal symptoms, it’s essential to consult with a healthcare professional for proper evaluation and management. Treatment for kidney stones often involves pain relief, hydration, and sometimes surgical procedures to remove or break up the stones. For constipation, dietary modifications, increased water intake, and over-the-counter or prescription laxatives may be recommended.

Preventing kidney stones includes staying hydrated, following a balanced diet, and maintaining a healthy lifestyle. To prevent constipation, focus on a diet rich in fiber, staying active, and drinking plenty of water.


In summary, kidney stones themselves are not a direct cause of constipation. While they can lead to various gastrointestinal symptoms, including nausea and vomiting, constipation is generally unrelated to the presence of kidney stones. If you are experiencing both kidney stones and constipation, it’s crucial to seek medical advice to address each condition properly. Remember to follow a healthy lifestyle and consult your healthcare provider for guidance on preventing and managing both kidney stones and constipation.
