The lower esophageal sphincter (LES) is a muscular ring that connects the oesophagus to the stomach. Its primary function is to allow food to pass through into the stomach and then close to prevent reflux. However, the LES can be damaged by certain medications, high-fat foods, and lifestyle factors, causing acid reflux and gastroesophageal reflux disease (GERD). To prevent and manage these conditions, specific exercises can strengthen the LES, including breathing exercises involving the diaphragm and Kegel exercises. Additionally, the anal sphincter, composed of thick bands of muscle surrounding the anus, can be consciously controlled and strengthened through exercises to improve bowel control and reduce the chance of leaking stool or gas.

What You'll Learn
Anal sphincter exercises
The back passage or anus has two rings of muscle around it: the internal sphincter and the external sphincter. The internal sphincter is an inner ring of muscle that usually remains closed until you need to empty your bowels. It is an involuntary muscle that relaxes automatically when you need to pass stool. On the other hand, the external sphincter is the outer ring of muscle that you can consciously control. This muscle can be exercised and strengthened to provide better support and potentially compress the internal sphincter to prevent leakage.
To exercise the external sphincter muscle, you can perform various exercises to make it thicker and stronger. These exercises aim to improve muscle control and speed up its reaction, helping with wind and stool control. Like any other muscle in the body, consistent practice will lead to a stronger sphincter muscle.
One recommended exercise is deep breathing, also known as belly breathing. This exercise can be done while lying down or standing. It involves learning to engage your stomach muscles and diaphragm through slow exhales with arm movements and vocalization. Working with a trained physical therapist can help you learn the correct techniques and ensure that your diaphragm and ribs are aligned correctly.

Pelvic floor exercises
To perform pelvic floor exercises, first identify the correct muscles. These are the muscles that control urine flow. One way to identify them is to start urinating and then stop. The muscles that you feel tighten are the pelvic floor muscles. Alternatively, women can insert a finger into their vagina and tighten the muscles as if they are holding in their urine, then let go. Men can do the same by inserting a finger into their rectum.
Once you have identified the correct muscles, you can perform the exercises. Begin by emptying your bladder. Then, tighten the pelvic floor muscles and hold for a count of 10. Relax the muscles completely for a count of 10. Repeat this 10 times, 3 to 5 times a day. It is important to keep your breathing regular and to ensure that only the muscles of the pelvic floor are being tightened. The abdominal and buttock muscles should remain relaxed.
For women, another way to perform these exercises is to place an index finger into the opening of the vagina and squeeze the pelvic floor muscles as if trying to tighten them around the finger and pull it up into the vagina. The tightness around the finger can be used to measure the strength of the muscles and how well you can hold the squeeze.
For men, first squeeze the rectum closed as if trying to stop passing wind while also trying to stop the flow of urine midstream. You should feel a sensation of 'squeeze and lift' as you close and draw up the back and front passages.
It may take several weeks or even months to see improvement, but these exercises have been shown to be effective at improving urinary continence.

Lower oesophageal sphincter exercises
The lower oesophageal sphincter (LES) is a muscular ring that connects the oesophagus with the stomach. Its function is to open when you swallow, allowing food to pass through the oesophagus and into the stomach, and then close to prevent reflux. However, the LES can become overly relaxed due to various factors, including certain medications, high-fat foods, herbs, caffeinated beverages, whole milk, tomatoes, and peppermint. This relaxation of the LES can lead to gastroesophageal reflux (GER) or gastroesophageal reflux disease (GERD), causing heartburn and acid reflux.
To address a weakened LES, specific breathing exercises involving the diaphragm can be beneficial. These exercises aim to strengthen the pressure of the lower oesophageal sphincter. A physical therapist can evaluate the position of your diaphragm and ribs and recommend specific exercises such as deep breathing or belly breathing, which can be performed while lying down or standing. These exercises focus on engaging the stomach muscles and can help alleviate the symptoms of GERD without the need for medication.
One study published in the American Journal of Gastroenterology involved participants practising breathing exercises, with half of them performing exercises that engaged the diaphragm, similar to those used by singers. Some exercises were done lying down, focusing on abdominal wall movement and relaxation of chest and rib muscles. Other exercises were done in a seated or standing position, incorporating slow exhales with raised arm movements and vocalization.
In addition to breathing exercises, dietary modifications can also help protect the LES. Reducing the consumption of high-fat foods can be beneficial, as they tend to cause the LES to relax. By avoiding trigger foods and incorporating specific breathing exercises into your routine, you can strengthen your lower oesophageal sphincter and alleviate the discomfort associated with acid reflux and heartburn.

Breathing exercises
While there are no physical exercises to strengthen the lower esophageal sphincter, certain breathing exercises can help relieve discomfort during a gastroesophageal reflux disease (GERD) attack.
One breathing exercise involves placing one hand lightly on your upper chest and breathing from your stomach area, ensuring your chest is not moving. Another way to do this exercise is to breathe into 'the back and sides of a waistcoat'.
To relax your sphincter muscle during a bowel movement, you can also try deep breathing. Breathe in slowly and deeply for 4 seconds, then exhale slowly for another 4 seconds. You can also try meditating to release tension in your muscles. Close your eyes and take slow, deep breaths through your nose. Focus on your breathing to clear your mind and relax your muscles.

Avoiding trigger foods
While there are exercises to strengthen the anal sphincter, there is little information on how to close the sphincter muscle through food. However, there are some suggestions on how to avoid constipation, which is a common cause of a weak sphincter muscle.
Constipation is a common problem that can be caused by a variety of factors, including diet. Certain foods can trigger constipation, making it difficult for the sphincter muscle to close properly. Here are some tips to help you avoid these trigger foods and improve your bowel health:
- Reduce your fibre intake: While fibre is essential for a healthy diet, too much can contribute to constipation. Consider cutting back on high-fibre foods such as fruits and vegetables, but ensure you still meet the recommended daily intake.
- Stay hydrated: Drink plenty of fluids, especially water, to keep your stool soft and easy to pass. Dehydration can lead to hard, dry stool that is difficult to pass and can put strain on the sphincter muscle.
- Limit dairy: Dairy products, such as cheese and milk, can be constipating for some people. If you suspect dairy is a trigger for you, try reducing your intake and see if your symptoms improve.
- Avoid processed foods: Processed and refined foods, such as white bread and pastries, are low in fibre and can contribute to constipation. Opt for whole grain, high-fibre alternatives instead.
- Manage your caffeine and alcohol intake: Excessive caffeine and alcohol consumption can dehydrate you and contribute to constipation. Limit your intake of coffee, tea, and alcoholic beverages, and ensure you stay properly hydrated by drinking plenty of water.
- Consider probiotics: Probiotics are live microorganisms that can help improve gut health and digestion. Include probiotic-rich foods in your diet, such as yoghurt, kefir, sauerkraut, and kimchi.
Remember, it is always best to consult with a healthcare professional or a dietician before making any significant changes to your diet. They can provide personalized advice and help you identify any specific trigger foods that may be contributing to your constipation.
