Keto And Appendicitis: Is There A Link?

The ketogenic diet is a low-carb, high-fat, and moderate-protein diet. It was originally developed for children with epilepsy but has since become a popular weight-loss diet. While the keto diet has many purported health benefits, some people wonder if it may also have some adverse effects, such as appendicitis. Appendicitis is a serious medical condition in which the appendix becomes swollen and inflamed, requiring immediate surgery. Although the exact causes of appendicitis are not always clear, it is sometimes due to an obstruction in the appendix or an infection. So, does the keto diet increase the risk of appendicitis?

Keto diet and constipation

The keto diet is a very high-fat, very low-carb, and moderate protein eating pattern. This way of eating induces a phenomenon called ketosis, where the body burns fat instead of glucose for energy. While the keto diet may help burn fat, it can also cause side effects related to your gastrointestinal (GI) tract reacting to the absence of carbs. One such side effect is constipation.

Constipation means having three or fewer bowel movements per week. Being constipated may also make your stools hard and lumpy and difficult to pass. This happens because the keto diet is typically low in fiber, and individuals following the diet may consume more dairy and drink less water. The combination of these factors can lead to constipation.

The keto diet consists of under 50 grams (g) of carbohydrates per day, mainly fats and proteins. Therefore, you run the risk of under-consuming fiber-rich foods. Consuming fiber is important because it encourages the movement of food through your digestive tract. Soluble fiber absorbs water, while insoluble fiber acts as a bulking agent.

Reducing your fiber intake may also alter your intestinal microbiota, which is partly responsible for breaking down food. This lack of fiber means up to 50% of people following a keto diet will experience constipation at some point.

To treat and prevent constipation while on the keto diet, you can:

• Add more dietary fiber through keto-friendly, fibrous foods such as non-starchy vegetables, berries, avocados, and nuts.
• Drink enough water.
• Exercise regularly, as aerobic exercise can improve constipation by encouraging your intestines to contract.
• Reestablish frequent bowel movements by drinking sufficient fluids and establishing a regular time for toilet breaks.
• Cut back on dairy, as it is a common reason for constipation due to lactose, which can be hard to digest and lead to bloating, gas, nausea, and constipation.

If constipation persists, it is recommended to speak to a healthcare professional, who may suggest a low-carb laxative or fiber supplement.

Keto diet and kidney stones

The ketogenic diet is a high-fat, very low-carbohydrate, and moderate-protein diet. It was initially developed for children with epilepsy but has since become a popular weight-loss diet. However, the keto diet has been linked to an increased risk of kidney stones.

Kidney stones are more common in people on the keto diet, with an estimated incidence of 5.9% at a mean follow-up time of 3.7 years. This is significantly higher than the incidence of kidney stones in the general population, which is about 1 in several thousand. The risk of kidney stones is similar in children and adults on the keto diet, at 5.8% and 7.9%, respectively.

Uric acid stones are the most common type of kidney stones in people on the keto diet, followed by calcium-based stones and mixed uric acid and calcium-based stones. The exact mechanism behind this increased risk is not fully understood, but it is believed to be related to hypocitraturia and acidosis, which are common in people consuming a high-protein and low-alkali diet.

Acidosis can lead to increased urinary calcium excretion and bone demineralization, contributing to the formation of calcium-based kidney stones. Hypocitraturia, or low levels of citrate in the urine, can also increase the risk of stone formation as citrate normally binds to calcium, lowering its concentration and inhibiting crystallization. Dehydration, another risk factor for kidney stones, may be particularly significant in people on the keto diet as ketosis can interfere with the normal thirst mechanism.

To prevent kidney stone formation, it is recommended to liberalize fluid intake and alkalinize the urine using oral potassium citrate. Regular monitoring of urine studies, including calcium-to-creatinine ratio and ultrasonography, is also advised to detect this complication early.

Keto diet and diabetes

The keto diet is a high-fat, very low-carbohydrate, and moderate-protein diet. It was originally developed for children with epilepsy, but it has since been studied for its effects on type 2 diabetes.

The keto diet derives its name from ketones, which are molecules formed when the body burns fat for energy instead of carbohydrates. On a typical diet, the body converts carbohydrates into glucose for fuel. However, on the keto diet, the body enters a metabolic state called ketosis, where it burns fat instead of carbohydrates. This shift from burning carbs to burning fat can take about three to seven days, and it is accompanied by symptoms like tiredness, nausea, dizziness, and difficulty concentrating, collectively known as the "keto flu."

Pros and Cons

The keto diet has been shown to be effective for blood sugar management and weight loss in people with type 2 diabetes. It may also lead to reduced dependence on diabetes medication and insulin. However, there are several drawbacks to consider. The keto diet can be difficult to stick to in the long term, and there is a risk of yo-yo dieting, which can be harmful to people with diabetes. Additionally, the diet may not provide adequate nutrients, and it can lead to constipation due to its low fiber content.

Other Considerations

The keto diet may not be suitable for everyone with diabetes. It can increase the risk of hypoglycemia (low blood sugar), especially if medication and insulin levels are not properly adjusted. It is crucial to closely monitor blood sugar and ketone levels while on the keto diet. Additionally, people with diabetes are already at a higher risk for high cholesterol and heart disease, so it is important to distinguish between "good" and "bad" fats when following this diet.

Alternative Dietary Options

The Mediterranean diet, a low-carb, moderately high-fat diet emphasizing vegetables, legumes, fruits, whole grains, olive oil, and fish, has been found to be as effective as the keto diet in controlling blood glucose levels and aiding weight loss. It is generally easier to follow and provides a wider range of nutrients.

While the keto diet can be beneficial for some people with type 2 diabetes, it is not a one-size-fits-all solution. It is essential to consult with a healthcare professional before starting any restrictive diet to ensure it aligns with individual health needs and goals.

Keto diet and heart disease

The ketogenic diet is a high-fat, very low-carbohydrate and moderate-protein diet. The diet's name comes from ketones, molecules formed when the body burns fat for its source of energy instead of carbohydrates.

The Ketogenic Diet and Heart Disease

The ketogenic diet has been shown to have a multifaceted effect on the prevention and treatment of cardiovascular disease. It has a beneficial effect on the blood lipid profile, even compared to other diets. It shows strong anti-inflammatory and cardioprotective potential, which is due, among other factors, to the anti-inflammatory properties of the state of ketosis, the elimination of simple sugars, the restriction of total carbohydrates and the supply of omega-3 fatty acids.

The ketogenic diet has a beneficial effect on blood pressure and other CVD risk factors through, among other aspects, weight loss. The evidence cited is often superior to that for standard diets, making it likely that the ketogenic diet shows advantages over other dietary models in the prevention and treatment of cardiovascular diseases.

However, the high ratio of fat to protein to carbohydrate distinguishes the keto diet from other weight loss diets. It's also what makes it so popular. You can eat high-fat foods that are more often considered diet-busters than boosters—like butter and bacon.

The keto diet virtually eliminates carbohydrates from your diet, which eliminates most fruits, many vegetables and all the nutrients they contain—vitamins, minerals, fibre and phytonutrients, too.

A dietitian at the Weight Loss Management Center at UW Medical Center-Roosevelt does not recommend the keto diet for weight loss. It's true that low-carb diets can lead to fast short-term weight loss, but most studies find that at a year or two out, people have put the weight back on.

Moreover, what you’re not eating can also increase your risk of heart disease. When you avoid whole grains, legumes, and fruit, you lose a lot of the dietary fibre that helps protect your heart. While individual results of the diet can vary widely in different people, most people will see a rise in their cholesterol level, even if they lose weight. For people with a history of heart disease or high cholesterol, this can be especially dangerous.

A recent study presented at the American College of Cardiology's Annual Scientific Session suggested that a "keto-like" diet may be associated with higher blood levels of "bad" cholesterol and a twofold heightened risk of cardiovascular events such as chest pain (angina), blocked arteries requiring stenting, heart attacks and strokes.

In summary, the keto diet can be beneficial for the prevention and treatment of cardiovascular disease. However, it is not recommended for weight loss and can increase the risk of heart disease.

Keto diet and inflammation

The ketogenic diet is a low-carbohydrate, high-fat, and moderate-protein diet. The body's transition from burning carbs to burning fat can take up to seven days, and during this period, people may experience the "keto flu", which can include symptoms like tiredness, nausea, dizziness, and upset stomach.

The keto diet has been linked to reduced inflammation, which is a key contributor to several diseases, including heart disease, diabetes, and cancer. The anti-inflammatory effects of the keto diet are thought to be related to three main drivers: insulin reduction, BHB synthesis, and glucagon increase.

Insulin reduction is one of the key benefits of the keto diet and has been linked to lower levels of pro-inflammatory cytokines such as TNF-α, IL-1α, IL-1β, IL-6, and leptin. These cytokines are associated with macrophage activation and increased production of inflammatory markers.

BHB (beta-hydroxybutyrate), the primary ketone body found in the bloodstream, has been shown to suppress the production of pro-inflammatory cytokines, including IL-1, IL-12, and IL-6. BHB also inhibits the release of IL-1β and IL-18, contributing to the anti-inflammatory role of the keto diet.

Additionally, the increase in glucagon that comes with reduced insulin levels has anti-inflammatory effects. Glucagon activates the cAMP pathway, which suppresses the release of pro-inflammatory mediators and promotes the production of anti-inflammatory cytokines.

The keto diet has also been linked to weight loss, which can further reduce inflammation. Obesity is associated with increased local and systemic inflammation, and weight loss can help reduce the load exerted on joints and improve outcomes in people with inflammatory arthritis.

While the keto diet has potential benefits in reducing inflammation, it is not without its drawbacks. The extreme restriction of carbohydrates can lead to the elimination of most fruits, many vegetables, and the nutrients they contain. It is important to consult with a healthcare professional before starting any restrictive diet like the keto diet.
