Risk Factors For Urinary Stone Formation In The Morbidly Obese

Obesity can increase the risk of urinary stone formation. Kidney or urinary stones are formed out of crystals in the urine.

The stones will be in the solid form, which are formed from the substances excreted in urine.

When these waste substances do not dissolve completely in urine, they form into microscopic particles and slowly grow into stones.

When water and other substances are out of balance, such as from dehydration, substances present stick together and build up to form stones.

In many cases, crystals will be very small and pass out your body without any harm. Sometimes, these crystals build up inside your kidney and larger stones will be formed.

Once the stone becomes too large, urine flow will be blocked to come out of kidney and therefore it can cause pain, pressure and infection. If the stone moves through the ureter tube from the kidney, it causes pain.

While moving if the stone gets stuck, infection occurs. Based on the size and place of stone, kidney damage can be caused if kidney stones are left untreated. When acid levels of the urine are too high, uric acid kidney stones will be formed.

According to the research, obesity increases the urination of calcium and uric acid, which results in risk of formation of calcium containing urinary stones. The other reason is, fat tissues decrease your body’s ability to respond to insulin, which can change your urine and can lead to development of kidney stones.

Women who gained weight more than 35 pounds since age 21 has increase of stone formation up to seventy percent compared to older women who stayed the same weight. High body mass index and waist size also contribute to the urinary stone formation.

100% of morbidly obese patients had at least one abnormality in their urine profiles that predispose them to urinary stone formation. Longitudinal studies will evaluate the impact of bariatric surgery on these underlying risks.For related information on urinary stone formation, visit:
