Mild swelling is normal during pregnancy, especially in the third trimester. However , sudden and severe swelling of the hands and face, called preeclampsia , is dangerous and can lead to high blood pressure and other serious complications for both mother and child. If you are pregnant and notice sudden swelling, contact your doctor immediately.
4. Swelling associated with skin changes
If the swollen area of your foot or ankle is also red, tender, or warm to the touch, you may have an infection called cellulitis . This infection of the deeper layers of the skin can spread quickly and, if left untreated, lead to more serious sepsis.
5. Sudden, unexplained swelling
If your feet swell suddenly and for no apparent reason (such as a long flight or a minor shock), it may be an allergic reaction. Swelling, itching, or hives after eating a new food or medication may be a sign of a serious allergic reaction that requires immediate medical attention.
6. Swelling and kidney problems
Your kidneys filter waste and excess fluid from your body. When kidney function is impaired, fluid can build up, causing significant swelling in your legs, feet, and ankles. If you notice persistent swelling along with other symptoms such as fatigue, changes in urination, or a metallic taste in your mouth, it could be a sign of kidney disease .
7. Swelling associated with liver symptoms
The liver plays an important role in regulating fluid balance. When liver damage occurs, it produces less albumin, a protein that contributes to fluid retention in the blood. This can lead to fluid loss in the legs, feet, and even the abdomen. If you experience swelling and yellowing of the skin (jaundice), abdominal pain, or fatigue, consult a doctor to rule out liver disease .
8. Swollen and painful joints
Swelling in the feet and ankles can be the primary symptom of inflammatory conditions such as arthritis or gout . If the swelling is accompanied by joint pain, stiffness, or tenderness, it may indicate an inflammatory process requiring medical treatment.
9. Swelling due to medication
Some medications can cause water retention as a side effect. The most common causes include blood pressure medications, antidepressants, and hormone therapy. While this side effect is often manageable, it’s important to talk to your doctor. They can determine if the swelling is a normal side effect or indicates a more serious problem and adjust your dosage or treatment accordingly.
When should you see a doctor?
Although swollen feet are often harmless, prevention is better than cure. Seek immediate medical attention if swelling:
- Accompanied by chest pain, shortness of breath or dizziness .
- Occurs in one leg only and is painful, red, or warm.
- Is sudden, severe, or unexplained.
- Accompanied by symptoms of a serious infection or severe allergic reaction.
Ignoring these warning signs can put your health at risk. By paying attention to your body and acting quickly, you can receive the right diagnosis and treatment, sleep soundly, and regain optimal health.
