Multiple sclerosis in women: symptoms, hormones, pregnancy and menopause

Why is multiple sclerosis more common in women?

Multiple sclerosis (MS) is a chronic immune-mediated condition affecting the central nervous system, including the brain and spinal cord.

In MS, the immune system mistakenly attacks myelin, the protective covering surrounding nerve fibers. This disrupts communication between the brain and other parts of the body.

Research shows that women are around three times more likely to develop MS than men.

Researchers believe that differences in immune responses, genetics, hormones, and environmental factors may contribute to this imbalance. However, the exact reasons are not fully understood.

Carenity explores this question in more detail in Multiple sclerosis: are women more affected?.

What are the symptoms of MS in women?

The main symptoms of multiple sclerosis are generally similar in women and men, although each person's experience is different.

Common MS symptoms in women include:

• Fatigue: Persistent exhaustion that can affect everyday activities.
• Vision problems: Blurred vision, double vision, or eye pain.
• Numbness and tingling: Changes in sensation affecting different parts of the body.
• Muscle weakness and stiffness: Difficulties with movement, balance, or coordination.
• Bladder problems: Urinary urgency, frequency, or difficulty emptying the bladder.
• Cognitive difficulties: Problems with concentration, memory, or information processing.
• Pain and sensory changes: Including nerve pain or uncomfortable sensations.

Some symptoms may fluctuate or worsen temporarily, while others can persist.

Importantly, these symptoms are not specific to MS. Experiencing fatigue, tingling, or dizziness does not necessarily mean someone has multiple sclerosis.

A diagnosis requires assessment by a neurologist and may involve MRI scans, neurological examinations, and other investigations.

Can menstrual cycles affect MS symptoms?

Some women living with MS notice that their symptoms become more noticeable before or during their periods.

Changes in hormone levels and body temperature may contribute to temporary increases in symptoms such as:

• Fatigue and exhaustion
• Muscle weakness
• Balance difficulties
• Low mood or irritability
• Increased sensitivity to existing symptoms

However, a temporary worsening of symptoms around menstruation does not necessarily indicate a new MS relapse.

For example, changes in body temperature can temporarily affect nerve signal transmission in people with MS, making existing symptoms feel worse.

If you notice a recurring pattern, keeping a symptom diary may help you identify changes throughout your menstrual cycle.

You can record your period dates, fatigue, pain, sleep quality, and any changes in mobility or concentration.

Discuss persistent or concerning symptoms with your neurologist or MS specialist, particularly if they are new or different from your usual pattern.

Multiple sclerosis and pregnancy: what should women know?

One common concern after an MS diagnosis is whether pregnancy is possible.

Multiple sclerosis does not usually affect fertility, and many women with MS have healthy pregnancies and babies.

Current evidence indicates that MS itself should not prevent someone from planning a family.

For women with relapsing MS, relapse activity often decreases during pregnancy, particularly in the later stages.

However, the risk of relapse may increase during the first few months after childbirth before returning toward the person's previous level.

This does not mean pregnancy permanently worsens MS. Research has not shown that pregnancy itself increases long-term disease progression.

Planning pregnancy while taking MS medication

One of the most important considerations is disease-modifying therapy (DMT).

DMTs are medications used to reduce MS disease activity and help limit future relapses or progression, depending on the type of MS.

Some treatments may be continued during pregnancy in selected circumstances, while others require changes before conception.

A 2026 expert clinical review on managing multiple sclerosis during pregnancy and the reproductive years provides updated recommendations on managing MS treatments before, during, and after pregnancy.

If you are planning a pregnancy, discuss your treatment with your neurologist or MS specialist early.

Never stop a disease-modifying treatment without medical advice, as suddenly discontinuing certain medications can increase the risk of disease activity returning.

Your healthcare team can also discuss breastfeeding, contraception, and postpartum monitoring.

For additional information, visit Carenity's multiple sclerosis treatment information and ask your MS team about the medications relevant to your situation.

How can MS affect intimacy and sexual health?

Multiple sclerosis can sometimes affect sexual well-being and intimate relationships.

Some women experience reduced sensation, vaginal dryness, discomfort, changes in sexual desire, or fatigue that makes intimacy more difficult.

Bladder symptoms, muscle stiffness, and concerns about body image may also influence confidence.

These difficulties are not inevitable, and support is available.

Depending on your symptoms, your healthcare team may suggest:

• Discussing symptoms openly: Your MS specialist or healthcare provider can help identify possible causes and treatments.
• Managing vaginal dryness: Suitable lubricants or moisturizers may improve comfort.
• Adapting intimacy: Choosing times when fatigue is less severe or adjusting activities can help.
• Seeking emotional support: Counseling or psychosexual therapy may be useful when intimacy or relationships are affected.

Sexual health is part of overall well being and deserves the same attention as other MS symptoms.

MS and menopause: why can symptoms be difficult to distinguish?

Menopause is another important stage for women living with multiple sclerosis.

Symptoms associated with perimenopause and menopause can overlap with MS, making it difficult to identify what is causing certain changes.

These may include:

• Fatigue and sleep disturbances
• Difficulty concentrating or memory problems
• Mood changes
• Bladder symptoms
• Changes in temperature sensitivity

For example, menopausal hot flashes may temporarily make existing MS symptoms more noticeable because heat can affect nerve signal transmission.

However, not every new symptom during menopause should be attributed to MS.

Research into whether menopause directly changes the long-term course of multiple sclerosis remains limited and sometimes conflicting.

Can women with MS use hormone replacement therapy?

Hormone replacement therapy (HRT) may be considered for managing menopausal symptoms in women with MS.

Having MS is not, by itself, a contraindication to HRT.

However, HRT is not an established treatment for MS disease activity, and evidence that it changes MS progression remains uncertain.

Your healthcare provider and MS team can discuss whether HRT is appropriate based on your symptoms, medical history, and individual risk factors.

How can women manage MS throughout different stages of life?

Although multiple sclerosis is unpredictable, personalized care can help women manage symptoms and maintain quality of life.

Useful approaches include:

• Keeping track of symptoms: Record changes in fatigue, mobility, sleep, mood, and menstrual or menopausal symptoms.
• Reviewing treatment regularly: Discuss whether your current MS treatment remains suitable as your needs change.
• Managing fatigue: Plan demanding activities around your energy levels and allow time for rest.
• Staying physically active: Appropriate exercise and physical therapy can support strength, balance, and well-being.
• Discussing reproductive health: Raise questions about contraception, pregnancy, breastfeeding, or menopause with your healthcare team.
• Looking after emotional well-being: Seek support if anxiety, low mood, or the uncertainty of MS becomes difficult to manage.

Carenity member Millie shares how she has learned to manage fatigue and establish boundaries in Multiple sclerosis: I'm strict with my rest because without it, I can't function at all.

Her experience illustrates how adapting everyday routines can be an important part of living with MS, although each person's needs will differ.

When should you speak to your neurologist or MS specialist?

If you notice new symptoms, changes in your usual MS pattern, or difficulties managing daily activities, contact your MS team.

Before your appointment, consider noting:

• New or worsening symptoms: When they began, how long they lasted, and whether they affected your usual activities.
• Hormonal patterns: Any connection with periods, pregnancy, postpartum changes, or menopause.
• Fatigue and sleep: Whether exhaustion is becoming more difficult to manage.
• Medication: Your current treatments, possible side effects, and any plans for pregnancy.
• Bladder and sexual health: Symptoms you may not have previously discussed.
• Personal priorities: Concerns about work, relationships, family planning, or independence.

Your neurologist can assess whether symptoms may indicate a relapse, a temporary worsening of existing symptoms, or another health condition.

If you develop new neurological symptoms that persist for more than 24 hours, contact your MS team promptly for assessment, particularly if there is no obvious explanation such as fever or infection.

Sudden facial drooping, weakness in one arm, speech difficulties, or sudden loss of vision require emergency assessment. Call 911, as these symptoms could indicate a stroke.

Understanding MS in women means looking beyond the diagnosis

Multiple sclerosis affects women in different ways throughout their lives. Hormonal changes, reproductive health, relationships, and everyday responsibilities can all influence how symptoms are experienced and managed.

Understanding these connections can help women recognize changes, ask informed questions, and work with their healthcare teams to find care that reflects their individual needs.

There is no single experience of MS in women, and there is no single approach that works for everyone.
