Kidney presentation to seniors
By lkidder - October 18, 2023

By Larry Kidder | More than 50 seniors listen as nephrologist Bob Soderblom, MD, explains kidney function, what can go wrong, and how to prevent problems.

On Wednesday, November 18, 2023, Bob Soderblom, MD, retired nephrologist, shared his knowledge and experience as a physician specialist in explaining kidney function, what can go wrong up to and including kidney failure, and how to help slow or prevent problems. More than 50 seniors were on hand to hear the presentation and ask follow-up questions.

Nephrologist Bob Soderblom makes a point regarding kidney function.

According to statistics presented by Dr. Soderblom, approximately 700,000 Americans are currently diagnosed with end-stage renal disease (ESRD). More than 500,000 are receiving dialysis, and life expectancy for dialysis patients averages less than three years.

Kidney disease is typically diagnosed in four stages, based on urine output. Nephrologists look for issues impacting urine production that happen outside the kidneys—such as poor circulation related to cardiac problems; within the kidneys—such as poor function in filtering various bodily fluids or kidney stones; and after the kidneys—such as urinary tract obstruction due to passing stones or (for men) enlarged prostates.

Two of the major chronic diseases tied to kidney failure include diabetes—especially Type 2 which is far more prevalent, and circulatory problems such as cardiac failure or high blood pressure.

Dr. Soderblom explains some human anatomy, showing where the kidneys are in relation to other organs in the abdomen.

One of the best preventive measures is drink plenty of water, which is about two liters a day for the average adult. Breathing alone accounts for a third up to a half liter per day of water loss—depending upon the level of activity. However, drinking too much water, known as hyponatremia, can be life-threatening, since sodium, potassium, and other electrolytes may be severely diluted and the kidneys overwhelmed.

On the middle Wednesday of each month, an expert is invited to share his or her ideas on a topic related to senior health, wellness, and vitality. The next presentation, organized by Loma Linda University Drayson Center's senior wellness program, will take place Wednesday, January 17, 2024. Watch for more details.

All presentations are held Wednesdays in Drayson Center's student lounge at 11:30 a.m.
