Constipation in Chronic Kidney Disease

Introduction

Patients with chronic kidney disease (CKD) frequently experience constipation, which can be attributed in part to their sedentary lifestyle, low intake of fiber and fluids, concurrent drugs (such as phosphate binders), and other comorbidities (such as diabetes). Constipation is generally seen to be a benign, self-limiting ailment.

Constipation's persistent symptoms have a severe negative impact on patient's quality of life and place a significant financial and social burden on them. Additionally, recent epidemiological research has shown that constipation is independently linked to poor clinical outcomes, including mortality, cardiovascular disease, and end-stage renal disease (ESRD). This association may be mediated by changes in the gut microbiota and an increase in the production of fecal metabolites.

Constipation in CKD may limit or even prevent these ancillary gastrointestinal tasks, which could lead to increased morbidity and death. The importance of the gut in the removal of uremic toxins and in maintaining acid-base and mineral homeostasis with deteriorating kidney function. The appropriate management of constipation in CKD may offer additional therapeutic benefits beyond its traditional defecation control, especially with the introduction of novel medication classes, some of which have distinctive renoprotective effects.

What Causes Constipation With Chronic Kidney Disease?

For some patients, constipation is a side effect of CKD. Those who have kidney illness may experience constipation for the following reasons:

1. Nutritional Regimens for the Kidneys:

Those on a typical American diet may find obtaining the necessary amounts of fiber challenging. Diabetics with restricted dietary options have historically been prohibited from consuming a lot of foods that are high in dietary fiber. It is safe to include fiber-rich foods like fruits and vegetables in the renal diet, though, as updated guidelines for those with chronic kidney disease are less stringent in this regard.

2. Co-occurring Illnesses:

Diabetes, hypothyroidism (a dysfunction where the thyroid gland fails to produce adequate thyroid hormone), and hypercalcemia (a disorder where the blood's calcium level rises excessively) are a few conditions that frequently co-occur with renal disease and can slow down the digestive tract. Constipation may result from a sluggish digestive system.

• Bacterial Imbalance in the Stomach: When the kidneys are not functioning properly, a bacterial imbalance in the stomach, known as dysbiosis, can happen. It occurs as a result of the kidneys' failure to filter germs. This results in an odd combination of germs in the gut, which may make one feel constipated.

• Drug Reactions: Secondary illnesses, including anemia (a disorder where there are not enough healthy red blood cells in the blood), gout (it is a severe form of arthritis brought on by crystals of uric acid that accumulate in and around the joint), or bone disease can arise in individuals suffering from kidney disease. Certain drugs, including blood pressure pills, iron supplements, antiemetic drugs, and calcium supplements, which are often taken for these secondary conditions, can make some patients constipated.

• Changeable Limitations: Particularly for those receiving dialysis, people with advanced kidney disease may need to limit their fluid intake. It could be challenging to stay hydrated enough to prevent constipation.

Is Constipation an Early Warning Sign of Kidney Disease?

Usually, constipation is not a warning indication of kidney disease.

Kidney illness is more likely to cause early signs like:

• Fever.

• Exhaustion.

• Disorientation.

• Rash.

• Itchy skin.

• Extremely pale complexion.

• Weakness.

• Inexplicable cramping in the muscles.

• Bone pain.

• Lack of urine production or excessive urine production.

• Unusual bleeding.

• Bleeding from the nose, back pain.

• Stomach ache.

• Lump in the stomach.

• Occasionally, bloody diarrhea.

• Appetite decline.

• Metallic aftertaste.

• Severe vomiting.

• Bodily edema.

• Hearing difficulties.

What Is Constipation?

Constipation indicates difficulty in stool passing. Constipation is generally defined as not passing more than three stools in a week or difficulty passing feces. Constipation can be brought on by a diet low in fiber, hydration, and activity. However, other health issues or specific medications could be the reason.

Treatments for constipation typically involve dietary and activity modifications or over-the-counter medications. A healthcare provider may recommend medications, dosage adjustments, or other treatments to alleviate constipation. Chronic constipation, also known as long-term constipation, may need to be treated with another illness or ailment that can exacerbate constipation.

What Is the Best Way to Treat Constipation With Chronic Kidney Disease?

Constipation treatment varies depending on several factors, although food and lifestyle modifications are frequently effective in relieving symptoms. Usually, doctors advise making lifestyle modifications first before recommending medicine. Constipation can be relieved by the following lifestyle modifications for patients with chronic renal disease:

Consuming Additional Fiber: One of the most effective strategies to eliminate constipation is ensuring the diet has adequate fiber. Waste is moved through the system with the aid of fiber. Many foods contain fiber, including whole grains, nuts, lentils, beans, oats, apples, pears, and vegetables.

Picking up More Activity: Exercise helps treat constipation as nutrition passes through the digestive tract more easily, and blood flow is improved with exercise. Even a tiny daily stroll will have an impact.

Increasing Fluids - Drinking more fluids is a great way to combat constipation. The optimal strategy for consuming adequate fluids to maintain the function of their digestive systems might be discussed with physicians by patients with chronic renal disease.

Try Probiotics - Probiotics are live bacteria present in fermented foods and can aid in relieving constipation. Try taking them. Foods that were fermented should be included in the diet, like tempeh, natto, miso, kimchi, yogurt, sauerkraut, and handmade pickles.

Use Over-the-counter (OTC) Medicine to Alleviate Symptoms: Over-the-counter (OTC) medicine to alleviate symptoms: An over-the-counter medicine may be helpful if the symptoms are severe and other strategies, like drinking more water or eating more fiber, have not helped. It is crucial, though, to avoid taking these drugs for more than a few days at a time. Supplemental fiber, stimulant laxatives, and stool softeners are available over-the-counter.

Prescription Strength Medication - If lifestyle modifications are insufficient, the physician may recommend prescription versions of any medicine.

Conclusion

Constipation is not necessarily a result of chronic renal disease. Constipation can result from various factors, including co-occurring conditions, drugs, renal diets, and fluid limitations. Therapy can provide relief and frequently includes dietary and lifestyle modifications, such as increasing fiber intake, exercising more, and drinking more water.

In most cases, pharmacological treatment is advised when dietary and lifestyle modifications alone are insufficient to relieve constipation symptoms. Unlike initial constipation, secondary constipation, which is more common in CKD patients, is unlikely to improve with non-pharmacological treatment by itself. For individuals with CKD, pharmacological therapies are frequently necessary for the management of constipation.
