Updated On

Constipation and fever are two common health issues that many people experience at some point in their lives. Constipation is a condition characterized by difficulty passing stool or infrequent bowel movements, while fever is an elevation in body temperature above the normal range. While these two conditions may seem unrelated, there is a surprising connection between them. In this article, we’ll explore the relationship between constipation and fever, and what you can do to prevent and treat constipation-induced fever.

Key Takeaways

  1. Constipation can sometimes lead to fever due to the build-up of toxins and inflammation in the body.
  2. Maintaining a healthy diet, staying hydrated, and practicing good bowel habits can help prevent constipation-induced fever.
  3. If you experience persistent fever or severe symptoms related to constipation, it’s important to seek medical advice.

Symptoms of Constipation

Constipation is a common digestive issue that can cause a range of uncomfortable symptoms, including:

  1. Difficulty passing stool: If you strain or have to push hard to have a bowel movement, you may be constipated.
  2. Infrequent bowel movements: Having fewer than three bowel movements per week is often considered constipation.
  3. Abdominal discomfort: Constipation can cause bloating, cramping, and a feeling of fullness in the abdomen.

Symptoms of Fever

Fever is a natural response by the body to fight off infection or illness. Common symptoms of fever include:

  1. Elevated body temperature: A temperature above 100.4°F (38°C) is generally considered a fever.
  2. Chills and sweating: As your body tries to regulate its temperature, you may experience chills or sweating.
  3. Body aches and fatigue: Fever can cause muscle aches, headaches, and a general feeling of weakness or fatigue.

Causes of Fever from Constipation

While constipation doesn’t directly cause fever, it can sometimes lead to complications that result in a fever. Here are some ways constipation can contribute to fever:

  1. Build-up of toxins in the body: When stool remains in the intestines for too long, it can allow toxins to build up and be reabsorbed into the bloodstream, potentially leading to fever.
  2. Inflammation in the intestines: Chronic constipation can cause inflammation in the intestines, which may trigger a fever as part of the body’s immune response.
  3. Infection due to fecal matter retention: In rare cases, severe constipation can lead to a blockage or impaction of fecal matter, which can cause an infection and resulting fever.

Treatment for Constipation-Induced Fever

If you’re experiencing fever as a result of constipation, the first step is to address the underlying constipation. Here are some strategies to help relieve constipation and reduce the risk of fever:

  1. Increase fiber intake: Eating more high-fiber foods, such as fruits, vegetables, whole grains, and legumes, can help promote regular bowel movements and prevent constipation.
  2. Stay hydrated: Drinking plenty of water and other fluids can help soften stool and make it easier to pass. Aim for at least 8 glasses of water per day.
  3. Use laxatives or stool softeners if necessary: Over-the-counter laxatives or stool softeners can help relieve constipation if increasing fiber and fluid intake isn’t enough. However, it’s important to use these products as directed and not rely on them long-term.

In addition to treating constipation, you can also manage fever with over-the-counter fever reducers like acetaminophen or ibuprofen. Be sure to follow the dosing instructions carefully and consult with your healthcare provider if your fever persists or worsens.

Prevention of Constipation-Induced Fever

The best way to prevent constipation-induced fever is to prevent constipation from occurring in the first place. Here are some tips for maintaining healthy bowel habits and reducing your risk of constipation:

  1. Maintain a healthy diet: Eating a balanced diet that includes plenty of high-fiber foods can help keep your digestive system running smoothly.
  2. Exercise regularly: Physical activity helps stimulate bowel movements and can prevent constipation. Aim for at least 30 minutes of moderate exercise most days of the week.
  3. Practice good bowel habits: When you feel the urge to have a bowel movement, don’t ignore it. Take your time in the bathroom and avoid straining or rushing.

When to Seek Medical Help?

While constipation and fever can often be managed at home, there are some situations where it’s important to seek medical attention. Contact your healthcare provider if you experience any of the following:

  1. Persistent fever despite treatment: If your fever lasts more than a few days or doesn’t respond to over-the-counter fever reducers, it’s important to consult with your doctor.
  2. Severe abdominal pain: If you experience severe or worsening abdominal pain along with constipation and fever, it could be a sign of a more serious condition like appendicitis or diverticulitis.
  3. Blood in stool: If you notice blood in your stool or on the toilet paper after a bowel movement, it’s important to contact your doctor right away, as this could be a sign of a more serious digestive issue.


While constipation and fever may seem like two separate health issues, they can sometimes be related. Constipation can lead to complications like a build-up of toxins or inflammation in the body, which can trigger a fever. By understanding the connection between these two conditions and taking steps to prevent and treat constipation, you can reduce your risk of constipation-induced fever.

If you’re experiencing persistent or severe symptoms related to constipation or fever, don’t hesitate to seek medical advice. Your healthcare provider can help determine the underlying cause of your symptoms and recommend the most effective treatment plan for your individual needs.

By prioritizing digestive health and practicing good bowel habits, you can keep your body running smoothly and reduce your risk of uncomfortable and potentially serious health issues like constipation-induced fever.
