what causes a kidney stone?

Metabolic issue.: Kidney stones are initiated by metabolic derangements in the handling of urinary oxalate, uric acid or calcium, for example. These derangements can be hereditary, and they allow for crystals of these substances to form. These crystals serve as a nidus for stone creation.

Minerals: A kidney stone is hard mass developed from crystals that separate from the urine within the urinary tract. Kidney stones may contain various combinations of chemicals. Most common type of stone contains calcium in combination with either oxalate or phosphate. These chemicals are part of a person's normal diet and make up important parts of the body, such as bones and muscles.

Can a kidney stone cause a miss period?

2 doctor answers3 doctors weighed in
Dr. Allen Seely
General Practice 31 years experience
UNLIKELY: A missed period (amenorrhea) is usually caused by pregnancy--so this needs to be ruled out first. Other causes incude being underweight (as in heavy duty exercise). Kidney stones are caused by dehydration, excess calcium (too many tums-antacids) etc.. So the 2 problems probably not related.

Can consumtion of amino acid cause kidney stone?

2 doctor answers4 doctors weighed in
Dr. Alvin Lin
Geriatrics 30 years experience
Maybe: You can't (shouldn't) avoid Amino Acids which are the building blocks to protein. Regardless of whether you're a omnivore or vegan, you still need protein and thus need to consume amino acids. However, an excess of protein complicated by inadequate fluids can lead to gout & uric acid stones. Check out http://www.Mayoclinic.Com/health/kidney-stones/ds00282 for more info.

Can stone in kidney cause night sweat?

1 doctor answer1 doctor weighed in
Dr. Ronald Hamner
Nephrology and Dialysis 43 years experience
Yes: If the kidney stone blocks the ureter, intense pain can cause intense sweating. Moreover, if the stone blocks the kidney from draining urine and the urine becomes infected, the infection can act like an abscess. Not only will fever and seats occur but the kidney can be permanently damaged.
