Certain foods may promote stone formation in people who are susceptible. This stone formation is enhanced when there is increased intake of calcium, calcium oxalate, uric acid or salt in our diet, with an inadequate intake of fluids. A positive family history (genetic tendency) also makes a person prone to kidney stone formation.Certain foods that increase the risk for kidney stone formation in susceptible individuals include:Spinach, rhubarb, chocolate, peanuts, cocoa, beet, coffee, cola, nuts, strawberries, tomato juice, grapefruit juice, apple juice, soda (acidic and contains phosphorus), all types of tea, and berries
Infection or obstruction may play a part in kidney stone formation also. Sometimes they occur when the level of blood calcium is abnormally high. Occasionally, stones may develop when the blood level of uric acid is too high, usually from over consumption of meat. Excessive dietary intake of calcium and oxalate and low fluid intake have also been associated with formation of stones. In most cases, however the cause is not known. It has been found that certain persons are having a tendency of forming recurrent urinary stones. Even after treating successfully once, they tend to form stones again and again.
- * Hereditary: 1] : People suffering from gout, parathyroid problems, inflammatory bowel diseases and chronic urinary tract infection are predisposed to stone formation 2) Increased urinary concentration due to dehydrations ? Most stones arise in the kidney when urine becomes supersaturated with salts and crystals that are capable of forming stones.
- Hyperparathyroidism may also lead to hyper calcuria.
- Increase of calcium intake i.e. more than the required amount (e.g. intake of too much of chocolates, strawberries, etc
- Urinary inadequate drainage ? slow obstructive urine flow will encourage salt precipitation due to stagnation
- Vitamin A deficiency
- Increased intake of vitamin D, Calcium, protein, tea or fruit juice
- Prolonged immobility where stone formation is due to hypercalcuria.
- Metabolic order
- Decrease in fluid intake may precipitate formation of stones
- Prolonged bed rest
- Chronic use of antacids containing calcium
