Do your shoes seem too small for no apparent reason?

Don’t worry—this temporary swelling is more common than you might think. But sometimes, it can reveal an underlying condition that shouldn’t be ignored. Here’s everything you need to know, explained with care.

Why Do My Hands or Feet Swell?

This phenomenon is called edema — a buildup of fluid in the tissues. The areas most often affected? The extremities, such as the hands, feet, ankles, and legs. It can be temporary and harmless… or a sign of something more serious.

Water Retention: The Most Common Cause

Sometimes, the body simply holds onto a little too much fluid. This can result from small everyday imbalances, such as:

• Sitting or standing for too long

• A diet too high in salt

• Not drinking enough water

• Hormonal changes (menstruation, pregnancy, etc.)

The best response: elevate your legs and drink water. Sometimes that’s all your body needs to rebalance itself!

Slowed Blood Circulation

When blood flow is poor, fluid can accumulate, especially in the legs:

• Venous problems (varicose veins, weak valves)

• Heart failure

• Presence of a blood clot (venous thrombosis)

In these cases, swelling often occurs on just one side and may be accompanied by pain or a feeling of heaviness.

Kidneys or Liver Under Strain

These two organs regulate the body’s fluids. When they don’t function properly:

• The kidneys may allow too much sodium and water to pass

• The liver may cause fluid to leak into tissues

Generalized, persistent swelling may be a signal that a medical checkup is needed.

A Blocked Lymphatic System

Lymphedema can appear after surgery, cancer treatment, or infection. It often shows up as:

• A feeling of tightness

• Thickened skin

• Reduced mobility

It usually affects only one arm or one leg.

Certain Medications

Yes, common treatments can also cause swelling, such as:

• Blood pressure medications (like calcium channel blockers)

• Corticosteroids

• Hormone therapy

• Diabetes medications

Never stop a prescribed treatment without medical advice — talk to your doctor if you’re unsure.

A Reaction to Injury

A sprain, insect bite, or infection can trigger natural inflammation in the body, leading to:

• Swelling

• Redness

• Pain or warmth

In these cases, the swelling is clearly localized and often appears suddenly.

What About During Pregnancy?

Mild swelling of the hands or feet is completely normal, especially in late pregnancy. But be careful:

If the swelling is sudden, uneven, or accompanied by headaches or high blood pressure, it may indicate preeclampsia. In that case, seek medical help immediately.

When Should You See a Doctor?

• If the swelling is sudden or unexplained

• If only one leg or hand is affected

• If you feel pain, warmth, or redness

• If you have a history of heart, kidney, or liver problems

• If the swelling persists despite rest

Helpful Habits to Adopt

• Regularly elevate your legs or hands

• Reduce salt and stay hydrated

• Wear compression socks if needed

• Move around a little every hour

• Apply something cold to painful areas

Your body is speaking to you — it’s up to you to listen with care and attention.
