Does eating too much sugar harm the kidneys?

According to Dr. Doan Du Manh, a member of the Vietnam Vascular Disease Association, a diet high in sugar can cause metabolic disorders by increasing various types of fats in the body, leading to weight gain and obesity. This is a leading factor in promoting the progression of type 2 diabetes.

Metabolic disorders and diabetes are significant causes of vascular damage, including renal vascular damage, leading to chronic kidney failure.

Studies show that consuming large amounts of glucose increases sodium absorption in the small intestine due to a co-transport mechanism, causing the kidneys to work harder to excrete the excess salt.

Hyperglycemia causes renal complications through two mechanisms: metabolic and hemodynamic.

Sugar inhibits the body's production of nitric oxide (NO), a compound that stimulates the constriction of blood vessel walls. Eating too much sugar stimulates the narrowing of blood vessels, causing high blood pressure, kidney disease, and accelerating the progression of chronic kidney failure.

Sugar, especially fructose, can increase the amount of calcium and oxalate in urine, facilitating the formation of calcium oxalate crystals and causing kidney stones.

You should limit sugary foods to protect your overall health and, in particular, your kidney health.

Foods high in sugar should be limited, such as industrially produced soft drinks including soda, milk tea, bottled fruit juices, and sugary carbonated beverages. Snack foods like cakes, cookies, candy, chocolate, peanut butter, and potato chips should also be avoided. Limit canned sauces and condiments, dried fruits, and dried cereals.

Smoothies and fruit juices are beneficial for health because they provide many vitamins and fiber. However, consuming too much of these drinks and fruits can also be harmful due to their high sugar content. It's best to avoid added sugar and choose fruits with low sugar content such as lemons, passion fruit, oranges, grapefruits, apples, papayas, strawberries, and watermelons.
