Swelling in different parts of the body can happen after eating salty food, sitting for too long or experiencing an allergic reaction. But when swelling keeps returning or affects several areas, it may be connected to an underlying medical condition. The location and speed of the swelling can provide important clues.
1. Kidney disease: The kidneys regulate fluid and salt levels. When their function becomes reduced, fluid may accumulate around the face, hands, legs and feet.
2. Heart failure: A weakened heart may struggle to pump blood effectively, allowing fluid to build up in the legs and sometimes the abdomen.
3. Liver disease: Advanced liver disease can reduce the production of proteins that help keep fluid inside blood vessels. This can contribute to swelling.
4. Allergic reactions: An allergic reaction can cause sudden swelling of the lips, eyelids, face or tongue. Swelling involving the tongue or throat, or difficulty breathing, is a medical emergency.
5. Thyroid problems: An underactive thyroid can sometimes cause puffiness around the face and other changes in the body.
6. Certain medications: Some medicines, including certain blood pressure drugs and hormones, may cause fluid retention or swelling.
Final thoughts: Swelling is not always caused by kidney disease, but persistent or unexplained swelling deserves medical assessment. If swelling appears suddenly around the lips or tongue, or you experience difficulty breathing, seek emergency care immediately. Do not take water tablets or herbal mixtures without professional advice.
