Why Am I So Tired With Diverticulitis?


Diverticulitis, a condition characterized by inflamed or infected pouches in the colon, can be a debilitating and exhausting experience. While abdominal pain is a well-known symptom of diverticulitis, many individuals also experience persistent fatigue. In this article, we will explore the reasons behind the fatigue associated with diverticulitis and discuss strategies for managing and alleviating this symptom.

Symptoms of Diverticulitis

The symptoms of diverticulitis can vary from person to person. It’s depending on the severity of the inflammation and infection. Here we will explore some common symptoms such as:

  1. Abdominal pain, typically on the left side of the lower abdomen
  2. Bloating and gas
  3. Nausea
  4. Diarrhea or Constipation
  5. Loss of appetite
  6. Vomiting
  7. Fatigue and weakness
  8. Diverticulitis can cause more serious conditions such as rectal bleeding, urinary
  9. Fever and chills
  10. High fever.

Causes of Diverticulitis

Although the exact cause is unknown, several factors may contribute to the development of diverticula, including a low-fibre diet, age-related weakening of the colon walls, obesity, and a sedentary lifestyle. These factors can increase pressure within the colon, causing the diverticula to become inflamed or infected.

1. Inflammation and the Immune Response:

Diverticulitis triggers an inflammatory response in the body as the pouches in the colon become inflamed or infected. This inflammation and the immune system’s response can lead to increased fatigue. The body’s energy resources are diverted toward fighting off the infection and repairing the affected tissues, leaving individuals feeling tired and drained.

2. Disrupted Sleep Patterns:

The abdominal pain and discomfort associated with diverticulitis can disrupt sleep patterns. Many individuals experience pain that worsens at night or have difficulty finding a comfortable sleeping position. Poor sleep quality or insufficient sleep can contribute to daytime fatigue and overall tiredness.

3. Nutritional Deficiencies:

During episodes of diverticulitis, individuals may experience a reduced appetite or have dietary restrictions. This can lead to inadequate nutrient intake, including essential vitamins and minerals necessary for energy production. Nutritional deficiencies, such as iron deficiency anemia, can contribute to fatigue and low energy levels.

4. Psychological Factors:

Living with a chronic condition like diverticulitis can have psychological effects, including increased stress, anxiety, and depression. These psychological factors can further exacerbate fatigue and make it more challenging to cope with the physical symptoms of the condition. Emotional and mental exhaustion can contribute to overall feelings of tiredness.

5. Medications and Treatment Side Effects:

Certain medications prescribed for diverticulitis, such as antibiotics or pain relievers, can have side effects contributing to fatigue. Antibiotics, for example, can disrupt the natural balance of gut bacteria, leading to digestive issues and fatigue. Additionally, the recovery period after surgery or invasive procedures for diverticulitis can also cause temporary fatigue as the body heals.

Treatments for Diverticulitis:

The treatment approach for diverticulitis depends on the severity of the condition and the presence of complications. Mild cases of diverticulitis may be managed with conservative measures, while more severe cases may require medical intervention or even surgery. Here are the primary treatment options:

1. Antibiotics:

If an infection is present, antibiotics are prescribed to combat the bacterial inflammation. The choice of antibiotics may vary based on the severity of the condition and the individual’s medical history.

2. Clear Liquid Diet and Bowel Rest:

In mild cases, a clear liquid diet is recommended to allow the bowel to rest and heal. This involves consuming clear fluids such as water, broth, and fruit juices while avoiding solid foods.

3. High-Fiber Diet:

Once the acute symptoms subside, gradually introducing a high-fiber diet can help prevent future episodes of diverticulitis. Fiber-rich foods, such as fruits, vegetables, whole grains, and legumes, promote regular bowel movements and reduce the risk of diverticula formation.

4. Pain Medication:

Over-the-counter or prescription pain medication may be recommended to alleviate pain and discomfort associated with diverticulitis. However, it is essential to consult a healthcare professional before taking any medications.

5. Hospitalization and Intravenous Therapy:

Severe cases of diverticulitis may require hospitalization for intravenous fluids, pain management, and close monitoring. This allows healthcare professionals to ensure proper hydration and administer stronger antibiotics, if necessary.

6. Surgery:

In rare cases or when complications arise, surgical intervention may be necessary. Surgery aims to remove the affected portion of the colon and may be performed laparoscopically or through open surgery, depending on the individual’s condition.

Managing Fatigue Associated with Diverticulitis:

  • Prioritize Rest:Listen to your body’s signals and allow yourself to rest and recover when needed. Incorporate regular breaks and sufficient sleep into your daily routine.
  • Balanced Diet:Focus on consuming a well-balanced diet that includes nutrient-rich foods to support energy levels. Consult with a healthcare professional or nutritionist for dietary guidance.
  • Stress Management:Engage in stress-reducing activities such as meditation, yoga, or deep breathing exercises to alleviate psychological fatigue.
  • Medication Management:Discuss any concerns or side effects of medications with your healthcare provider. They may be able to adjust dosages or explore alternative options to minimize fatigue.
  • Support Network:Seek support from friends, family, or support groups to help manage the emotional aspects of living with diverticulitis and alleviate mental exhaustion.


Fatigue is a common symptom experienced by individuals with diverticulitis. Understanding the underlying causes, such as inflammation, disrupted sleep patterns, nutritional deficiencies, psychological factors, and medication side effects, can help individuals better manage their fatigue. By implementing strategies to support overall well-being, individuals can alleviate fatigue and improve their quality of life.
