What Is MDS (Myelodysplastic Syndrome)?

MDS refers to a group of disorders that affect how blood cells are formed in the bone marrow. In simple terms, the bone marrow doesn’t produce enough healthy blood cells—or produces cells that don’t function properly.

There are three major types of blood cells:

Red blood cells (carry oxygen)

White blood cells (fight infection)

Platelets (help blood clot)

In MDS, one or more of these may be affected, leading to symptoms that develop gradually over time. It’s considered a chronic blood disorder, and while it may progress slowly, early awareness is key for managing it effectively.

Why MDS Is Called a “Silent” Condition

The early stages of MDS often don’t produce dramatic symptoms. Instead, individuals may experience general fatigue, frequent infections, or bruising—things that can be attributed to everyday stress, aging, or other causes.

That’s what makes it “silent.” The signs are easy to explain away, but they may be pointing to something deeper.

Common Early Signs of MDS

Here are some of the most reported early symptoms—especially in people over the age of 60, when MDS becomes more common.

1. Persistent, Unusual Fatigue

Feeling tired after a busy week is normal. But persistent fatigue—especially when sleep isn’t helping—could be a sign that your red blood cell count is lower than it should be.

Low red blood cells (anemia) are a common early feature of MDS and can cause:

Shortness of breath after mild activity

Pale skin

General lack of energy or motivation

2. Frequent Infections or Slow Recovery

White blood cells are your body’s defense system. In MDS, when those cells aren’t functioning properly, you may get sick more often—even from minor exposure.

Some people notice:

Recurring colds or sinus infections

Long recovery times after illness

Low-grade fevers with no clear cause

If you’re constantly fighting off bugs or feel “run down” all the time, it’s worth discussing with a provider.

3. Easy Bruising or Bleeding

Platelets help your blood clot. When platelet levels are low, even small bumps can cause unexpected bruising or prolonged bleeding.

Early signs include:

Nosebleeds

Bleeding gums during brushing

Tiny red dots on the skin (petechiae)

These signs are easy to overlook—but they’re worth noting if they appear repeatedly.

4. Shortness of Breath

Many people with MDS describe feeling winded or out of breath even after light activity. This isn’t always chest pain—it’s more like a lack of endurance or air.

This happens when anemia affects oxygen delivery in the bloodstream. It may seem like poor fitness, but if it develops suddenly or worsens, it may be something more.

5. Pale or Washed-Out Appearance

Lower red blood cell counts often show in the skin tone. You might notice:

A pale or grayish look to the face

Lightening in the lips or eyelids

Dark under-eye circles that persist despite rest

These changes are usually gradual, but noticeable over time.

6. Unusual Aches or Bone Marrow Pressure

While rare in early stages, some individuals report a dull ache in bones or joints, especially in the hips or lower back.

This sensation is not sharp pain, but more of a pressure or stiffness that doesn’t match recent activity.

MDS Symptoms in Women

MDS can affect men and women, but some studies suggest that women may present slightly different or more subtle symptoms at first.

In women, fatigue and low stamina are frequently the earliest complaints. Since these signs are often attributed to stress, menopause, or sleep issues, MDS may go undiagnosed for longer.

That’s why pattern recognition is important—if multiple symptoms show up or persist despite lifestyle changes, it may be time to look deeper.

What Causes MDS?

While the exact cause isn’t always clear, there are known risk factors:

Age (most common over 60)

Prior chemotherapy or radiation

Long-term exposure to chemicals (like benzene)

Genetic predisposition in rare cases

Some people develop secondary MDS as a result of prior cancer treatment. Others develop it without any identifiable trigger.

When To Talk To a Doctor

MDS can only be diagnosed through a combination of:

Blood tests (to check for anemia, low white cells, or platelets)

Bone marrow biopsy (to assess marrow function and cell development)

It’s not something to self-diagnose—but knowing the signs can help you start a more informed conversation with a healthcare provider.

Ask about:

Unexplained fatigue

Frequent infections

Easy bruising

Worsening shortness of breath

You don’t have to mention MDS—just describe what you’re noticing and how long it’s been happening.

What Happens After Diagnosis?

Treatment varies based on the type and risk category of MDS. Options may include:

Supportive care (like transfusions)

Medications to boost blood cell production

Low-dose chemotherapy in some cases

Monitoring if symptoms are mild

The approach is always individualized. Some people live with mild MDS for years with little disruption, while others need more frequent care.
