Muscle Development And Constipation: Is There A Link?

can muscle development cause constipation

Constipation is a common issue that can be caused by a variety of factors, including diet, travel, aging, medication, and underlying medical conditions. While muscle development does not directly cause constipation, there is a link between constipation and muscle function, particularly in the pelvic floor and digestive tract. Pelvic floor dysfunction can lead to constipation, and constipation can also cause or be caused by anismus, a condition where the muscles and nerves in the pelvic floor fail to coordinate correctly for bowel movements. Additionally, certain medications that affect muscle contractility, such as antihypertensives, can contribute to constipation. Understanding the interplay between muscle development and constipation can provide insights into the management and treatment of this common condition.

Pelvic floor dysfunction

PFD can cause difficulty in releasing a bowel movement, an incomplete bowel movement, and urine or stool leakage. It can also lead to constipation, which can further cause or be caused by PFD. Other symptoms of PFD include frequent bathroom visits, straining or pushing to pass a bowel movement, and having to change positions on the toilet or use your hand to eliminate stool.

The causes of PFD are not well understood, and no specific factor has been identified as the cause. However, multiple factors have been discussed, including hypertonicity symptoms associated with voiding and defecation difficulties, which may be related to poor evacuation techniques. Pregnancy, childbirth, obesity, and chronic constipation can also cause changes in pelvic floor muscles, leading to PFD.

Treatment for PFD can vary from medication to rehabilitative physiotherapy, and even surgery. A combination of these options is often used for effective control of the disorder. Treatment for PFD that affects defaecation involves understanding a patient's diet, lifestyle, and bowel habits, and teaching them how to make dietary and lifestyle adjustments, as well as undergo anorectal biofeedback to improve their control over abnormal bowel habits. Patients with bowel incontinence are taught to improve pelvic floor and anal muscle strength, while those with obstructed defaecation learn coordination methods to relax the pelvic floor muscles when passing motion.

Laxatives and constipation

Constipation can be caused by a variety of factors, including muscle development, and can be treated with laxatives. Laxatives are available over the counter in pharmacies, grocery stores, and online. They may be labelled as laxatives, stool softeners, or fibre supplements. While laxatives are generally safe for adults experiencing occasional constipation, they should not be given to children unless recommended by a paediatrician. It is also important to consult a healthcare provider before taking laxatives during pregnancy or while on prescription medication, as they can interfere with certain drugs.

Laxatives work by increasing the water and fat absorbed by stool, softening it and making it easier to pass. They may also stimulate the nerves that control the muscles in the colon, forcing it into motion and moving the stool along. Bulk-forming laxatives are generally considered the gentlest type and are recommended as a first option unless otherwise advised by a healthcare provider. These laxatives add soluble fibre to the stool, drawing water from the body and making it bigger and softer. This increase in size stimulates the colon to contract and push out the stool.

It is important to read the label and follow the directions on the medication to prevent side effects. Bulk-forming laxatives, for example, can cause dehydration if they draw too much water from the body. If a laxative is not working or is causing side effects such as severe diarrhoea, it is recommended to consult a healthcare provider. Additionally, if constipation persists despite trying different laxatives, it is advisable to see a doctor for further evaluation and potential alternative treatments.

Constipation can be a symptom of pelvic floor dysfunction, a common condition that affects the pelvic floor muscles and nerves, making it difficult to have a bowel movement. Anismus, or dyssynergic defecation, is a type of pelvic floor dysfunction that can cause or be caused by chronic constipation. Biofeedback therapy is the most effective treatment for anismus, and healthcare providers may also suggest experimental treatments such as botulinum toxin injections.

Intestinal obstructions

There are several possible causes of intestinal obstructions. One of the most common causes is abdominal adhesions, which are fibrous bands of tissue that form in the abdomen after surgery. Hernias are another common cause, where a segment of the intestine protrudes through a weakened abdominal wall, becoming trapped or pinched. Volvulus, a condition where the intestine twists around itself, can also cause intestinal obstructions.

Other causes include intussusception, a rare disorder where one part of the intestine slides inside another part; scarring from tears, infections, or surgeries; inflammatory bowel diseases such as Crohn's disease and diverticulitis; and foreign objects accidentally or intentionally swallowed. Certain medications and conditions can also increase the risk of intestinal obstructions.

Symptoms of intestinal obstructions include severe abdominal pain, vomiting, constipation or inability to pass stool, loss of appetite, feelings of fullness or bloating, loud digestive sounds, and an inability to pass gas. If you are experiencing any of these symptoms, seek immediate medical attention.

Irritable bowel syndrome

I did not find sufficient information on whether muscle development causes constipation. However, I found information on irritable bowel syndrome (IBS), a group of symptoms that affect the digestive tract.

Symptoms of IBS

Recurring constipation or diarrhoea may indicate IBS. Other common symptoms include abdominal pain or cramps, excess gas and bloating, mucus in stool, and the feeling of being unable to empty the bowels. These symptoms can appear frequently or during flare-ups, and they can vary depending on the type of IBS.

Diagnosis of IBS

There is no single test to diagnose IBS. Doctors will review symptoms, medical and family history, and perform a physical exam, looking for a pattern in the symptoms. They may also order tests to rule out other health problems, such as blood and stool tests.

Treatment of IBS

IBS can be treated through diet and lifestyle changes, medicines, probiotics, and mental health therapies. Dietary changes may include eating more fibre, avoiding gluten, or following a low FODMAP diet.

Anismus (dyssynergic defecation)

Anismus, also called dyssynergic defecation, is a functional defecation disorder. It occurs when the muscles and nerves in the pelvic floor fail to coordinate correctly to have a bowel movement, causing pelvic floor dysfunction. It can cause or be caused by chronic constipation.

People with anismus share symptoms of severe constipation, including less than three bowel movements a week, excessive straining to defecate, hard and painful stools, and a bloated stomach. Dyssynergic defecation is estimated to account for 15% to 25% of all chronic constipation cases, with constipation affecting 10% to 20% of people worldwide. It is about twice as common in women as in men, and its prevalence increases with age, particularly after 65.

Anismus can take different forms. In some cases, the muscles that usually hold in stool fail to relax during bowel movements, a condition called hypertonic pelvic floor. In other cases, these muscles may even tighten instead, a phenomenon known as paradoxical contraction. Additionally, some individuals with anismus are unable to coordinate their muscles to generate sufficient force to effectively pass stool. Furthermore, about half of those with this condition have an impaired ability to sense the urge to defecate or to detect whether they have fully evacuated their bowels.

Before diagnosing dyssynergic defecation, healthcare providers will typically rule out other common structural and metabolic causes of constipation. This may involve several generic rectal exams, such as a digital rectal exam (DRE) and a sigmoidoscopy, which involves inserting a small lighted scope into the rectum. If these initial tests do not reveal any obvious causes, more specific tests may be conducted, such as anorectal manometry, which measures the contractions and relaxations of the anal and rectal muscles.

Biofeedback therapy is considered the most effective treatment for anismus. While laxatives and pharmaceuticals for constipation may be suggested, these medications have not been specifically studied for dyssynergic defecation. However, they can help prevent stool from becoming too impacted to pass. Experimental use of botulism toxin injections for anismus has shown mixed results.
