What is Diverticulosis?

Diverticulosis is the formation of abnormal pouches in the wall of your bowel. These pouches, called diverticula, can develop in any part of your digestive tract, but they’re most commonly found in the large intestine.

When you have diverticulosis, these pouches can become inflamed or infected, leading to a condition called diverticulitis.

It’s important to note that diverticulosis itself is usually asymptomatic, meaning it doesn’t cause any noticeable symptoms. However, when diverticulitis occurs, it can cause symptoms such as abdominal pain, bloating, constipation, diarrhea, flatulence, and minor bleeding in the feces.

If you experience any of these symptoms, it’s important to seek medical attention for proper diagnosis and treatment.

Symptoms and Causes

If you have diverticulitis, the symptoms can include constant pain in the lower left side of your abdomen, nausea, vomiting, fever, abdominal tenderness, and changes in your bowel movements.

Diverticulitis occurs when small pouches in the digestive tract become inflamed or infected. It’s most commonly found in the lower part of the large intestine. The pain may also be more intense on the right side in people of Asian descent.

Risk factors for diverticulitis include aging, obesity, smoking, lack of exercise, and a diet high in animal fat and low in fiber.

Complications of diverticulitis can include abscesses, bowel blockages, and abnormal passageways.

Regular exercise, a high-fiber diet, drinking plenty of fluids, and quitting smoking can help prevent diverticulitis. Early diagnosis and treatment are important to prevent complications.

Diverticulosis vs Diverticulitis

You should understand the key differences between diverticulosis and diverticulitis in order to manage your condition effectively.

Diverticulosis refers to the development of small pouches, called diverticula, in the colon wall. It’s usually asymptomatic and may be detected during routine tests.

On the other hand, diverticulitis occurs when these diverticula become inflamed or infected. This condition causes sudden and severe abdominal symptoms, such as abdominal pain, fever, nausea, and vomiting.

While diverticulosis can be managed through dietary changes, such as consuming a high-fiber diet, diverticulitis often requires treatment with antibiotics.

In severe cases or when complications arise, hospitalization, surgery, or other interventions may be necessary.

Being aware of the symptoms and seeking early treatment can help reduce the risk of complications associated with diverticulitis.

Best supplements for diverticulosis

If you’re looking for the best supplements to manage diverticulosis, consider incorporating psyllium husk into your diet. It’s a natural fiber that can help regulate bowel movements and reduce symptoms.

Probiotics are also beneficial, as they promote a healthy gut microbiome and may alleviate inflammation.

Glutamine, omega-3 fatty acids, and butyrate have shown promise in reducing inflammation and promoting gut health as well.

1. Psyllium Husk

Adding psyllium husk to your diet can help prevent and manage diverticulosis by promoting efficient digestion and reducing pressure on your intestinal walls.

Psyllium husk acts as a valuable supplement for diverticulosis because it helps move stool through your system smoothly, preventing the formation of pouches on the intestinal walls. By guiding the stool directly through the intestines, psyllium husk also lowers the risk of diverticulitis.

It does this by preventing the stool from accumulating in the pouches, which is believed to be a major cause of infection. Adding psyllium husk to your diet can be an effective way to manage diverticulosis and reduce the risk of complications.

Here’s our recommended Psyllium Husk supplement:

Psyllium husk powder, 2 Pounds

  • Clean Ingredients: It contains no GMOs, preservatives, artificial colors or flavors, soy, dairy, or gluten.
  • Versatile Usage: Available in powder form for higher concentration, quick absorption, and ease on the stomach, offering various ways to consume.

2. Probiotics

The best supplements for diverticulosis include probiotics such as Lactobacillus acidophilus and bifidobacteria.

These probiotics help maintain the health of the intestines and can be beneficial for individuals with diverticulosis.

In a study, it was found that people who’d diverticulitis were more likely to remain symptom-free after one year when they were treated with specific probiotics like Lactobacillus casei and mesalazine.

However, it’s important to note that some probiotics may not be suitable for individuals with severely suppressed immune systems. Therefore, it’s recommended to consult with a healthcare professional before starting any probiotic supplementation for diverticulosis.

Overall, incorporating probiotics into your diet may be a helpful addition to managing diverticular disease and promoting intestinal health.

3. L-Glutamine

Glutamine is an amino acid that’s naturally found in the body and plays a role in maintaining proper intestinal function.

While there’s currently no evidence that glutamine specifically helps reduce symptoms of diverticular disease, it may still be beneficial for overall intestinal health.

Recent research indicates that glutamine, an amino acid, benefits gut health by supporting the microbiome, mucosal wall integrity, and reducing inflammation via the gut-brain connection through the vagus nerve. [1]

Glutamine has been also found to be a super important amino acid for our guts. It helps our gut cells grow, keeps them strong, and stops inflammation. When we’re really sick or have gut problems, our glutamine levels drop. Scientists have even looked into giving people more glutamine to help them get better. [2]

It’s important to note that individuals with certain medical conditions, such as diabetes, seizures, liver disease, or a history of mania or manic episodes, shouldn’t take glutamine. As with any supplement, it’s always best to consult with your healthcare provider before starting any new regimen.

Recommended L-Glutamine Supplement

3. Omega-3 fatty acids

Taking omega-3 fatty acids as a supplement can provide relief from inflammation caused by diverticulosis.

Omega-3 fatty acids, commonly found in fish oil, have been shown to have anti-inflammatory properties. By incorporating omega-3 fatty acids into your diet or taking a supplement, you may help reduce inflammation and alleviate symptoms associated with diverticulosis.

It’s important to note that omega-3 fatty acids are different from omega-6 fatty acids, which can actually increase inflammation.

Therefore, it’s recommended to focus on sources of omega-3 fatty acids, such as fish oil, rather than omega-6 fatty acids found in meats and dairy products.

However, if you’re on blood-thinning medication, it’s important to consult your doctor before taking high doses of a fish oil supplement, as omega-3 fatty acids have a blood-thinning effect and can interact with certain medications.

Overall, incorporating omega-3 fatty acids into your diet can be a beneficial way to manage inflammation caused by diverticulosis.

Recommended Omega-3 Supplement:

4. Butyrate

Butyrate, a short-chain fatty acid, has beneficial effects on intestinal cells and plays a role in maintaining intestinal health. Numerous studies support the value of butyrate in digestive disorders, including diverticulosis.

Butyrate, produced in our guts when we eat fiber, is like fuel for cells in our colon. It also has some special powers – it can stop certain processes that cause inflammation and talk to specific receptors.

Having enough butyrate is really important for our gut health. It helps our gut cells work well, reduces inflammation, keeps our gut strong, and makes sure our gut bugs behave.

Studies have shown that a sodium butyrate supplement can also reduce episodes of diverticulitis, the inflammation of these pouches.

Try incorporating a daily dose of a butyrate supplement into your routine to help improve symptoms of diverticulosis.

Recommended Butyrate Supplement:

5. Aminosalicylic Acid

Aminosalicylic Acid can be an effective supplement for managing symptoms of diverticulosis.

Researchers conducted two studies involving over two hundred patients and found that Aminosalicylic Acid, also known as mesalamine, helped control abdominal pain in patients with diverticulitis. It has anti-inflammatory and immunomodulatory properties, making it a potential treatment option for this condition.

In addition, a low dose of 3mg/day of Aminosalicylic Acid had a preventive effect. This means that it could potentially help reduce the occurrence of diverticulitis in individuals with diverticulosis. These findings suggest that Aminosalicylic Acid may be a beneficial supplement for individuals managing symptoms of diverticulosis.

However, it’s important to consult with your healthcare provider before starting any new supplement regimen to determine if Aminosalicylic Acid is appropriate for your specific condition.

6. Curcumin

If you’re looking for a natural supplement for managing symptoms of diverticulosis, consider incorporating curcumin into your daily routine.

Studies in animal models have shown that curcumin can inhibit tumor necrosis factor-alpha, which is one of the inflammatory chemical messengers associated with diverticular disease and acute diverticulitis. This suggests that curcumin may have anti-inflammatory effects that could potentially help alleviate symptoms of diverticulosis.

While more research is needed to fully understand the benefits of curcumin in humans with diverticular disease, preliminary evidence is promising.

Curcumin is a compound found in turmeric, a spice commonly used in Indian cuisine. It’s available in supplement form and can be easily incorporated into your daily routine.

As always, it’s important to consult with your healthcare provider before starting any new supplement regimen.

Recommended Curcumin Supplement

7. Magnesium

To regulate your bowel movements and alleviate symptoms of diverticulosis, consider incorporating magnesium supplements into your daily routine, as it supports neuromuscular system function and regulates peristalsis.

Magnesium is essential for muscle and nerve functions, including those of the digestive system. Insufficient magnesium can lead to stiffness, tightening, and spasms in the muscles.

Magnesium glycinate is a better alternative to magnesium salts, as it’s more absorbable and provides additional benefits for mood and sleep regulation. It effectively crosses the intestinal membrane and the blood-brain barrier.

Taking magnesium in divided doses is more effective for bowel movement regulation, as small doses are absorbed by the body to regulate muscle tone. High doses of magnesium may have an osmotic effect, causing water-pulling and laxative effects.

Overall, magnesium supplementation can be beneficial in managing diverticulosis and promoting bowel regularity.

Recommended Magnesium Supplement

8. Vitamin D

If you’re looking to increase your vitamin D levels to reduce the risk of diverticulitis and its complications, consider taking vitamin D supplements or incorporating vitamin D-rich foods into your diet such as fatty fish, beef liver, eggs, cheese, some mushrooms, and fortified foods.

Vitamin D plays a crucial role in maintaining overall health, including the health of the digestive system. Low levels of vitamin D have been associated with an increased risk of diverticulitis and its complications.

To ensure an adequate intake of vitamin D, you can opt for supplements that contain either vitamin D-2 or vitamin D-3.

Foods to avoid with diverticulosis

When managing diverticulosis, it’s important to be mindful of your diet to prevent flare-ups and complications. While individual sensitivities may vary, here are some general guidelines on foods to avoid:

  1. Processed Foods: Limit or avoid foods that are high in refined sugars, unhealthy fats, and artificial additives. This includes many packaged snacks, sugary beverages, and processed meats.
  2. Red Meat: While lean meats in moderation can be part of a healthy diet, red meats like beef and pork may be harder to digest for some people with diverticulosis. Try to choose lean cuts and limit your intake.
  3. Dairy Products: Some individuals with diverticulosis may be lactose intolerant or sensitive to dairy products. If you experience digestive discomfort after consuming dairy, consider switching to lactose-free options or plant-based alternatives like almond or soy milk.
  4. Spicy Foods: Spicy dishes can irritate the digestive tract and potentially trigger symptoms. If you enjoy spicy foods, try to moderate your consumption and pay attention to how your body reacts.
  5. Nuts and Seeds: Historically, doctors often recommended avoiding nuts and seeds due to concerns about them getting lodged in diverticula and causing inflammation. However, recent research suggests that small, well-chewed quantities of these foods may not be problematic for most people with diverticulosis. Consult with your healthcare provider for personalized advice on nuts and seeds.
  6. Popcorn: The hulls of popcorn can be sharp and may pose a risk of getting stuck in diverticula, potentially leading to inflammation or infection. If you enjoy popcorn, make sure it’s well-popped to minimize the risk.
  7. Alcohol: Excessive alcohol consumption can irritate the gastrointestinal tract. If you drink alcohol, do so in moderation, and be mindful of how it affects your symptoms.

It’s crucial to note that individual dietary triggers can vary, and what works for one person may not work for another. It’s advisable to keep a food diary to track which foods seem to aggravate your symptoms and discuss your findings with a healthcare professional.

They can help you create a personalized diet plan that suits your specific needs and helps manage your diverticulosis effectively.

Additionally, staying well-hydrated and maintaining a healthy weight can also contribute to better overall digestive health.
