kidney stone?

 Foods that increase kidney stone risk include those high in oxalates (like spinach, nuts, and chocolate), sodium (processed and fast foods), animal protein (red meat, fish), and added sugars (sodas and sugary drinks). Excessive caffeine, alcohol, and certain phosphorus-rich processed foods can also contribute to stone formation. Limiting these items and focusing on a balanced diet can help reduce the risk. 

What is the first symptom of a kidney stone?

Kidney stones form in the kidneys. Symptoms may start as stones move into the ureters. The ureters are thin tubes that let urine pass from the kidneys to the bladder. Symptoms of kidney stones can include serious pain, upset stomach, vomiting, fever, chills and blood in the urine.
