Here is a section from the autobiographical chapter of Dr Bernstein's book "Diabetes Solution" where he mentions hair loss from the legs and other diabetic complications, many of which he was able to reverse once he began testing his bg and lowering his carb intake:
"I spent the next year checking my blood sugars 5–8 times each day.
Every few days, I’d make a small, experimental change in my diet or insulin regimen to see what the effect would be on my blood sugar. If a change brought an improvement, I’d retain it. If it made blood sugars worse, I’d discard it. I discovered that 1 gram of carbohydrate raised my blood sugar by 5 mg/dl, and ½ unit of the old beef/pork insulin lowered it by 15 mg/dl (milligrams per deciliter). Blood glucose values in this book are as a rule given in mg/dl. If you should need to translate from one to the other, 1 mmol/l = 18 mg/dl.
Within a year, I had refined my insulin and diet regimen to the point that I had essentially normal blood sugars around the clock. After years of chronic fatigue and debilitating complications, almost overnight I was no longer continually tired or “washed out.” People commented that my gray complexion was gone. After years of skyhigh readings, my serum cholesterol and triglyceride levels had now not only dropped, but were at the low end of the normal ranges.
I started to gain weight, and at last I was able to build muscle as readily as nondiabetics. My insulin requirements dropped to about one-third of what they had been a year earlier. With the subsequent development of human insulin, my dosage dropped to less than onesixth of the original. The painful, slow-healing lumps the injections of large doses of insulin left under my skin disappeared. The fatty growths on my eyelids from high cholesterol vanished. My digestive problems (chronic burning in my chest and belching after meals) and the proteinuria that had so worried me eventually vanished. Today,my results from even the most sensitive kidney function tests are all normal.
The cystoid macular edema that I thought as recently as twelve years ago was irreversible has finally reversed. My deformed feet, the calcified walls of arteries in my legs, and the loss of hair on my lower legs are not reversible and still remain.
I had the new sensation of being the boss of my own metabolic state, and began to feel the same sense of accomplishment and reward I had in engineering when I solved a difficult problem. I had taught myself how to make my blood sugars whatever I wanted them to be and was no longer on the roller coaster. Things were finally under my control."
