Kidney (Renal) Failure
Kidney failure can occur from an acute event or a chronic condition or disease. Prerenal kidney failure is caused by blood loss, dehydration, or medication. Some of the renal causes of kidney failure include sepsis, medications, rhabdomyolysis, multiple myeloma, and acute glomerulonephritis. Post renal causes of kidney failure include bladder obstruction, prostate problems, tumors, or kidney stones.Treatment options included diet, medications, or dialysis.
High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms. Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure. The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater. If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.REFERENCE: CDC. High Blood Pressure. Updated: Nov 13, 2017.

Other treatment options include prescription medications.
Why Are Calcium Levels Low in Renal Failure?
Renal failure usually causes calcium imbalance. During renal failure, the kidneys may no longer filter out extra phosphorus and remove it from the body or from urine. Over time, phosphorus may increase in the blood. Calcium and phosphorous usually keep each other in check.
Polycystic Kidney Disease (PKD), ARPKD, and ADPKD
Polycystic kidney disease (PKD) is characterized by numerous cysts in the kidneys. Polycystic kidney disease is a genetic disorder.

Symptoms include headaches, urinary tract infections, blood in the urine, liver and pancreatic cysts, abnormal heart valves, high blood pressure, kidney stones, aneurysms, and diverticulosis. Diagnosis of PKD is generally with ultrasound, CT or MRI scan. There is no cure for PKD, so treatment of symptoms is usually the general protocol.

Symptoms of granulomatosis with polyangiitis include bloody sputum, fatigue, weight loss, joint pain, sinusitis, shortness of breath, and fever. Granulomatosis with polyangiitis may be fatal within months without treatment. Treatment aims to stop inflammation with high doses of prednisone and cyclophosphamide.
Diabetes and Kidney Disease
In the United States diabetes is the most common cause of kidney failure. High blood pressure and high levels of blood glucose increase the risk that a person with diabetes will eventually progress to kidney failure. Kidney disease in people with diabetes develops over the course of many years. albumin and eGFR are two key markers for kidney disease in people with diabetes. Controlling high blood pressure, blood pressure medications, a moderate protein diet, and compliant management of blood glucose can slow the progression of kidney disease. For those patients who's kidneys eventually fail, dialysis or kidney transplantation is the only option.
Sex, Urinary, and Bladder Problems of Diabetes
