Some people say it's a pain worse than childbirth. Sometimes kidney stone pain
starts as a dull ache, but it can quickly escalate to severe cramping or sharp,
wincing pain. You usually feel it in your back or side, underneath your rib cage.
The pain can radiate into your lower abdomen or groin .
Anyone may develop a kidney stone, but people with certain diseases and
conditions (see below) or those who are taking certain medications are more
susceptible to their development. Urinary tract stones are more common in men
than in women. Most urinary stones develop in people 20 to 49 years of age, and
those who are prone to multiple attacks of kidney stones usually develop their
first stones during the second or third decade of life. People who have already
had more than one kidney stone are prone to developing further stones.
CAUSES OF KIDNEY STONE
1_ Chronic diseases such as diabetes and high blood pressure ( hypertension )
are also associated with an increased risk of developing kidney stones.
2_ Hypercalciuria (high calcium in the urine), another inherited condition,
causes stones in more than half of cases. In this condition, too much calcium is
absorbed from food and excreted into the urine, where it may form calcium
phosphate or calcium oxalate kidney stones.
3_ Kidney stones form when your urine contains more crystal-forming
substances — such as calcium, oxalate and uric acid — than the fluid in your
urine can dilute. At the same time, your urine may lack substances that prevent
crystals from sticking together, creating an ideal environment for kidney stones
to form.
4_ Other conditions associated with an increased risk of kidney stones include
hyperparathyroidism, kidney diseases such as renal tubular acidosis, and other
inherited metabolic conditions, including cystinuria and hyperoxaluria.
5_ Digestive diseases and surgery. Gastric bypass surgery, inflammatory bowel
disease or chronic diarrhea can cause changes in the digestive process that
affect your absorption of calcium and water, increasing the levels of stone-
forming substances in your urine.
6_ Dehydration. Not drinking enough water each day can increase your risk of
kidney stones. People who live in warm climates and those who sweat a lot may
be at higher risk than others.
7_ Gout results in chronically increased amount of uric acid in the blood and
urine and can lead to the formation of uric acid kidney stones.
8_ Certain diets. Eating a diet that's high in protein, sodium (salt) and sugar may
increase your risk of some types of kidney stones. This is especially true with a
high-sodium diet. Too much salt in your diet increases the amount of calcium
your kidneys must filter and significantly increases your risk of kidney stones.
