Symptom 17: Swelling in the Legs and Ankles
Swelling in the legs and ankles can be a symptom of kidney stones, particularly if the stone obstructs the flow of urine and impacts kidney function. Kidney stones are hard deposits formed by minerals and salts that crystallize within the kidneys. When these stones partially or completely block the flow of urine, they can cause immense pain and discomfort, and in some cases, lead to swelling in the lower extremities. The kidneys play a crucial role in regulating fluid balance in the body; when their function is compromised, fluid can accumulate in the lower extremities, leading to swelling or edema.
Edema, or the buildup of excess fluid in the body’s tissues, is often a result of poor kidney function. The kidneys are responsible for filtering waste and excess fluids from the blood, which are then excreted as urine. When kidney stones block the urinary tract, this filtration process is disrupted, and fluid can accumulate in the legs and ankles. This swelling can be particularly noticeable at the end of the day, when gravity has had the most impact on the fluid distribution in the body.
While swelling in the legs and ankles can result from various causes, such as venous insufficiency, congestive heart failure, or lymphedema, it should not be ignored when accompanied by other kidney stone symptoms. These symptoms may include severe pain in the side and back, pain that radiates to the lower abdomen and groin, blood in the urine, nausea, vomiting, and frequent urination. In some cases, fever and chills may also be present, which can indicate a urinary tract infection caused by the kidney stone.
If you notice swelling in your lower extremities along with other indications of kidney stones, it is essential to seek medical attention for proper evaluation and treatment. Treatment options for kidney stones can range from pain management and increased fluid intake to more invasive procedures like extracorporeal shock wave lithotripsy, ureteroscopy, or even surgery. Timely diagnosis and treatment can help prevent further complications, such as kidney damage or recurrent urinary tract infections, and ultimately alleviate the discomfort and swelling associated with kidney stones.
