A diet for oxalates in urine is the main method of treating symptoms that have caused an increased content of the above substances in the excreta.
Oxalates in urine are oxalic acid salts found in tests. They are ammonium or calcium compounds. Increased excretion of oxalates by the body occurs in a disease called oxaluria.
The causes of oxaluria can be primary and secondary.
Primary causes include hereditary factors. Namely, the disease oxalosis, which has a genetic nature. It manifests itself in the disruption of oxalic acid metabolism in the body. The disease provokes symptoms of urolithiasis, and can later develop into renal failure.
Secondary oxaluria is acquired in nature and is caused by several factors:
- Consuming large amounts of synthetic vitamin C.
- Increased content of foods rich in oxalic acid and vitamin C in the diet.
- Existing chronic diseases that increase the amount of oxalates in the urine: diabetes mellitus, pyelonephritis, inflammatory bowel disease, ulcerative colitis, Crohn's disease.
- An increase in the content of oxalates in urine can be observed with a deficiency of vitamin B6 in the body.
- Operations performed on the intestines can also provoke an increase in the excretion of oxalates in the urine.
Diet for oxalates in the kidneys
In order for oxalate stones to dissolve, you need to adhere to the following dietary conditions:
- The diet for oxalates in urine should contain plenty of fluids. Therefore, the patient needs to drink at least two and a half to three liters of liquid per day. Two liters of this should be pure still water.
- Limit the amount of food consumed at one time. Meals should be fractional, 5 times a day.
- At the very beginning of the transition to dietary nutrition, you should try to eat once a day.
- When eating a single meal, you need to drink freshly prepared juices, which help remove oxalates from the patient's kidneys. The amount of juice per day should be at least one and a half glasses. Freshly squeezed juice is taken immediately after preparation, 20-30 minutes before meals.
- After limiting the amount of food consumed and introducing freshly prepared juices, you need to take a decoction of chickpea flour for several days. An infusion of radish seeds or leaves is also suitable. The proportions for preparing a decoction and infusion are: one tablespoon of dry mass per one glass of water.
- It is necessary to drink diuretic infusions so that the removal of oxalate stones from the kidneys is successful. All diuretic teas are taken one tablespoon and brewed with one glass of boiling water. Then the infusion is left for half an hour in a thermos and taken warm, half a glass 30 minutes before meals three times a day.
Here are some diuretic infusions that are recommended for patients:
- take corn silk, mint leaves and goldenrod in equal proportions;
- useful mixture – dill seeds, knotweed grass, strawberry leaves;
- collection - horsetail herb, dill seeds, strawberry leaves.
- Dairy products should be consumed only in the first half of the day.
- The caloric content of the daily diet should be no more than 2800 - 3000 calories.
What is the diet for oxalates?
If the patient has an elevated oxalate content in the urine, changing the diet in this case is an effective measure to restore health. In secondary oxaluria, diet is one of the main methods of treatment.
To answer the question: “What is the diet for oxalates in urine?”, we need to focus on the principles of therapeutic nutrition when this disease appears.
- Products containing oxalic acid and promoting its formation in the body are completely excluded from the patient’s diet.
