Multiple sclerosis (MS) affects everyone with the condition differently and can sometimes cause a variety of symptoms that may seem unusual or surprising. Several members of MyMSTeam describe experiencing a warm, reddened face, especially during bathroom trips.

“Does anyone else have facial flushing when using the bathroom?” one member asked. “I get this flushing, sometimes only on one side of my face and one ear and sometimes on both sides of my face and both ears, whenever I use the bathroom.”

“I have these exact same symptoms,” another member replied. “Anyone ever find out why these symptoms happen?”

Read on for more information about facial flushing (redness or warmth in the face) during bowel movements in people with MS, including what might cause this symptom, how to manage it, and when to see a healthcare provider.

What Causes a Flushed Face During Bowel Movements in MS?

When you have MS, your immune system (your body’s natural defense against illness) mistakenly attacks the myelin (protective covering) of nerves in your central nervous system, which includes the brain and spinal cord. This damage disrupts the way nerves send signals, causing a variety of symptoms that can affect almost any part of your body, including the digestive system.

For some people with MS, this nerve damage can lead to bowel problems like constipation. Bladder problems and bowel dysfunction are also common due to muscle control issues or nerve damage. Constipation may be worsened by limited physical activity, certain medications, or dietary factors such as low fiber.

Chronic constipation can lead to significant straining during bowel movements, which may also involve increased pressure in the rectum. This straining can make you hold your breath briefly or change your breathing pattern, which might lead to a flushed face. Some people jokingly refer to this as “poop face” — the temporary redness or warmth that can appear on your face when you’re pushing too hard. Straining also impacts the pelvic muscles and sphincter, which may worsen incontinence and contribute to flushing due to changes in blood flow and pressure.

What Are Other Causes of a Flushed Face?

Constipation is a common problem for people with MS and a potential cause of facial flushing. But you may be curious about what else a flushed face is a symptom of. There are other reasons why your face might turn red or feel warm, some related to MS and some unrelated. These include:

• Spasticity (muscle stiffness or tightness) — A common MS symptom, this can increase muscle tension and can sometimes affect the autonomic nervous system, which regulates automatic functions like blood flow, digestion, and bladder control.
• Temperature dysregulation — Damage to certain nerves in the brain may result in problems maintaining a normal body temperature and in reddening of the face.
• Abnormal sensations — People with MS may experience unusual sensations, such as burning, in any body area, which could feel warm to the touch.
• Certain medications — Side effects of dimethyl fumarate (Tecfidera), a treatment option for MS, include red, warm, or burning skin. Other types of drugs, such as calcium channel blockers and steroids, can also cause flushing.
• Rosacea — This inflammatory skin condition can cause symptoms of blushing or flushing.
• Menopause — Hot flashes and flushing are common symptoms of menopause, due to hormonal changes.
• Certain foods and beverages — Alcohol, dairy products, spicy foods, and hot beverages can be triggers for facial flushing in people with or without MS.

Managing Facial Flushing During Bowel Movements in MS

Facial flushing can occur for many reasons in people with MS, and it can be related to the condition itself, other health issues, or unrelated factors. Fortunately, there are strategies for addressing the symptom.

If your face tends to flush when you’re using the toilet, addressing bowel problems like constipation may help. Here are some lifestyle changes you can try:

• Drink plenty of fluids — Aim for six to eight glasses of water a day to keep your body hydrated and your digestive system working smoothly.
• Eat more fiber — Include foods like fruits, vegetables, and whole grains in your diet to help prevent constipation.
• Stay physically active — Regular movement, like walking or stretching, can help keep your digestion on track.
• Consider over-the-counter (OTC) treatments — Fiber supplements may ease constipation and reduce the need to strain. Laxatives or enemas may also help. However, it’s important to speak with your healthcare provider before trying these options, as even supplements and OTC treatments can cause unwanted side effects and medication interactions.

When To Seek Medical Advice

Keeping a symptom diary may help identify potential triggers for facial flushing and associated issues, such as bloating, fatigue, or changes in your bathroom routine. Write down when the flushing happens and note related factors, such as stress, bathroom habits, or specific activities. With this knowledge, you can avoid triggers that cause or worsen symptoms. Note whether flushing occurs alongside neurological symptoms like dizziness or pain.

If new symptoms arise or existing ones worsen, it’s important to consult a healthcare professional, such as a neurologist. For constipation, they may recommend additional treatments or strategies, such as biofeedback for issues with your pelvic floor or medications targeting bowel and bladder control.

MS is a complex condition that requires a holistic approach, encompassing not just medical treatments but also lifestyle and supportive therapies. By working closely with your care team, you can manage symptoms effectively and maintain your quality of life.
