Regular consumption of tea and coffee can have more negative effects on the body than you might think, potentially leading to conditions directly related to the urinary system, such as kidney stones. Having stones in the urinary tract can lead to various complications, including urinary tract infections, reduced kidney function, and even chronic kidney failure, which can be life-threatening.
Stones typically begin in the kidneys and can move to the renal pelvis, ureters, bladder, and urethra. Small stones may pass on their own during urination, but larger stones can cause blockages. The causes of kidney stones include a variety of factors such as environment, genetics, lifestyle, and dietary habits.
Eight major contributors to kidney stones
- Genetics: Certain hereditary diseases can increase the risk of urinary stones.
- Age: Most common in working-age adults, particularly those aged 40-60.
- Gender: Males are 2-3 times more likely to develop stones than females.
- Diet: The type and quantity of food affect the excretion of substances like calcium, phosphate, urate, and oxalate. When present in abnormal amounts, these substances can combine to form hard crystal aggregates that grow into stones.
- Fluid Intake: Insufficient water intake (less than 2 liters per day) increases the risk of stone formation.
- Certain Medications: Some medications can contribute to stone formation.
- Urinary Tract Infections: These can lead to changes in urine composition, promoting stone formation.
- Anatomical Abnormalities: Structural issues in the urinary tract can facilitate stone development.
Symptoms of urinary stones
Symptoms depend on the size and location of the stones and the degree of blockage they cause. Early on, small stones may pass unnoticed, but as stones grow, they can cause significant issues:
- Pain in the lower back or abdomen, depending on stone location.
- Burning sensation during urination and difficulty urinating.
- Blood in urine (80-90% of patients).
- Cloudy urine due to sediment.
- Infection symptoms like fever and foul-smelling urine.
- Complete urinary blockage if stones obstruct the urethra or severe kidney blockage.
In cases where stones are located in the kidneys or ureters, patients may experience severe, intermittent pain, sweating, and blood in the urine. If left untreated, kidney damage can occur, leading to chronic kidney disease.
Treatment for urinary stones
Various treatment options are available, depending on the stone’s type, size, location, hardness, and any associated kidney swelling or inflammation:
- Symptomatic treatment: For stones smaller than 4 mm, increasing fluid intake can help flush them out.
- Medications: Suitable for small, round, smooth stones with minimal pain and inflammation.
- Minimally invasive procedures: Techniques like shock wave lithotripsy can break up stones under 2 cm without surgery.
- Surgical options: Open surgery is suitable for large stones or severe inflammation. Endoscopic procedures can remove stones from the bladder and ureters.
Prevention of kidney stones
- Stay hydrated: Aim for more than 2 liters of urine output daily by drinking over 8 glasses of water.
- Balanced diet: Eat a variety of nutritious foods, especially fruits and vegetables.
- Limit certain foods: Reduce intake of red meats, animal fats, and foods high in uric acid.
- Avoid high-oxalate foods: These include spinach, chocolate, tea, nuts, apples, asparagus, broccoli, and more.
- Increase fiber intake and exercise regularly: This supports overall health and kidney function.
- Regular check-ups: Annual health assessments are vital, especially for those with a history of stones.
