Know Your Kidneys
The kidneys are part of the urinary system, responsible for urine production. The urinary system consists of four parts:
- Kidneys
- Ureters
- Bladder
- Urethra
Important Functions of the Kidneys
The primary function of the kidneys is to produce urine, which helps eliminate waste from the body resulting from the metabolism of various nutrients. They also help maintain the balance of water and electrolytes. Additionally, kidneys produce substances that regulate blood pressure and stimulate red blood cell production. When kidney function declines, issues such as high blood pressure and anemia may arise. Poor dietary habits, including a diet high in spicy foods and fast foods rich in sugar, salt, and fats, can lead to complications that increase the risk of kidney disease.
Main symptoms of poor kidney health
- Swelling: Initially, swelling may occur around the eyes and face, progressing to the legs and feet. Pressing on the skin in these areas may leave a dent, indicating significant swelling. This is often caused by excess fluid and salt in the body and could signal kidney, heart, or liver issues. Consult a doctor if widespread swelling occurs.
- Blood in urine and foamy urine: If urine appears red or contains blood, or if it is foamy due to excess protein (albumin), it’s important to seek medical advice, as these can indicate various conditions including kidney inflammation, stones, or tumors.
- Frequent urination: Increased urination, especially if exceeding 3 liters per day or waking up at night to urinate, may be an early sign of kidney dysfunction. While frequent urination can also result from diabetes or other conditions, it’s essential to consult a doctor for a proper assessment.
- Reduced urination: If you are drinking plenty of fluids but not urinating much or at all, this may indicate poor kidney function or urinary obstruction. Seek medical help immediately.
- Lower back or flank pain: Pain located in the lower back or flank area may indicate kidney issues.
Strategies to Slow Kidney Decline
- Control high blood pressure: Maintain blood pressure below 140/90 mmHg through medications and reduced salt intake.
- Avoid smoking, alcohol, and excessive caffeine: Limit sodium intake to less than 2 grams per day (equivalent to 1 teaspoon of salt).
- Manage Diabetes: Keep blood sugar levels below 120 mg/dL.
- Diet for blood sugar control: A low-protein diet can help slow kidney decline. Foods like starches, mung beans, and sago can provide sufficient energy. If kidney function is severely impaired, limit high-potassium fruits and avoid dairy, tofu, and egg yolks due to high phosphorus content. Manage fluid intake to avoid swelling.
- Avoid high-sodium condiments: Steer clear of salty sauces, pickled vegetables, processed meats, and salted eggs or fish.
- Medication: ACE inhibitors or ARBs, prescribed by a doctor, can help slow kidney decline, but be cautious about potential high potassium levels as a side effect.
