- The Homepage of Dr. Lyn Sutherland

Welcome to the homepage of the late Dr. Lyn Sutherland, MD. She passed away peacefully on February 16, 2005.

During the last years of her life, Lyn found great joy in the development of this site. It was a great way to spread her wealth of knowledge on what interested her the most, the study of several renal syndromes (especially Bartter’s and Gitelman’s) across the globe. I had the great pleasure of being her tool to reach her faithful and loyal followers.

Lyn studied Medicine at the University of Toronto and did post-grad work with the Hartrofts who were pioneers in the study of Juxtaglomerular cells and the renin-angiotensin-aldosterone system. She worked with them at The Hospital for Sick Children in Toronto, but later practised medicine in Northern Ontario where she was associated with Women’s College Hospital, also a Toronto Hospital.

She will be greatly missed.

We have recently lost two more members of our family. Gerry Roderick Singleton, and his wife of 37 years, Irene Singleton both passed away several months apart. Irene was Lyn's daughter, and one of her primary caregivers during Lyn's final years. Gerry was Lyn's devoted son-in-law, and was constantly at Lyn's side until the day she passed on. This website was conceived and developed out of their home, where Lyn resided for several years. I spent alot of time over there and I miss them dearly. I have added a dedication page to Irene and Gerry that can be viewed here.


Website Started August 4, 2003 - Completed February 16, 2005

This website provides us with Lyn's illustration of some of the kidney problems that lead to Bartter’s and Gitelman’s. Even under the best conditions the kidney is in many respects a “grossly inefficient” organ, according to an early physiologist, Homer Smith, as quoted by Schnerman (2003).

Smith also told us that the kidney demands one quarter of the blood put out by the heart so that every minute it pours 125 cc of water into the renal tubules.  Of this stream of water 99% must be reabsorbed.  Because of the circuitous pattern of filtration and reabsorption of water nearly half a pound of glucose and over three pounds of salt (sodium chloride) must also be reabsorbed every day. (It is, therefore, no wonder that any defect interfering with the reabsorption of sodium in particular, will give rise to the most unfortunate of consequences.) Besides the water and salt many other substances – for example, amino acids and phosphate – must also be saved from urinary loss and absorbed again from the tubular stream.
