Restriction of salt consumption

• Protection of the kidneys – Excessive salt consumption burdens the kidneys, as they have to work harder to excrete excess sodium. This can lead to a deterioration of kidney function in the long term. • Prevention of kidney stones – High salt intake increases calcium excretion through urine. This can contribute to the formation of kidney stones, which cause painful discomfort. • Reduction of high blood pressure – A diet high in salt can increase blood pressure, negatively affecting kidney circulation and overall urological health. • Reduction of bladder irritation – High salt concentrations in the urine can irritate the bladder lining and exacerbate symptoms such as frequent urination or burning during urination. • Better fluid balance in the body – Salt binds water in the body. Excessive intake can lead to fluid retention and affect the natural balance of the urinary tract.

A high salt intake causes the kidneys to excrete more sodium through the urine. This process can promote the formation of crystals, which can develop into kidney stones. Additionally, a high salt intake can disrupt the body's water balance, leading to reduced urine production or an increased concentration of irritants in the urine.

Particularly in people with existing kidney disease or bladder problems, a high-salt diet can worsen symptoms. Studies show that excessive sodium intake can also negatively affect the function of the bladder mucosa, which can promote the development of overactive bladder symptoms.

Many processed foods contain high amounts of salt, often without being consciously noticed. Particularly salt-rich foods are:

1. Ready meals and fast food – Frozen pizzas, ready-made soups, snacks, and fast-food products often contain large amounts of hidden salt.
2. Sausages and smoked products – Salami, ham, and smoked meats have a high salt content, which can strain the kidneys.
3. Cheese and dairy products – Especially hard cheese, processed cheese, and some types of yogurt contain a lot of sodium.
4. Bread and baked goods – Many types of bread and pastries contain high amounts of salt, which is often not directly tasted.
5. Salty snacks – Chips, pretzels, salted nuts, and crackers are typical sources of high salt intake.
6. Sauces and ready-made dressings – Soy sauce, ketchup, ready-made salad dressings, and seasoning mixes can be hidden sources of salt.

1. Prefer fresh, unprocessed foods

   • Fruits, vegetables, legumes, and fresh meat naturally contain little salt and are healthy alternatives to processed products.

2. Season with herbs instead of salt

   • Parsley, basil, garlic, lemon juice, or turmeric offer a flavorful alternative to salt and are gentle on the urinary tract.

3. Conscious use of convenience products

   • Packaged foods should be checked for their salt content. Many products contain hidden sodium, which can be replaced by homemade dishes.

4. Drink more water

   • Adequate fluid intake helps flush excess sodium from the body and keeps the urinary tract healthy.

5. Gradual reduction of salt consumption

   • The sense of taste adapts over time to a lower-salt diet. A gradual reduction can help ease the transition.

Excessive salt intake can cause long-term health problems. It is advisable to seek medical advice if:

• Symptoms such as persistent water retention, swollen legs, or high blood pressure occur. • Recurrent kidney stones have been detected or there is an increased risk of their formation. • Bladder irritations or urinary tract infections are exacerbated by a high-salt diet.
