Marcus Welby, M.D.: Let Ernest Come Over

Detective Sergeant Ernest Jackson, a black policeman who has worked twice as hard as his white colleagues to reach that rank, drives hundreds of miles to see Dr. Welby. Why? Because he is under consideration for a promotion to Detective Lieutenant, the first black man to hold that rank in his command, but if word of his health problems gets back to his commanders, it will damage or destroy his chances. Dr. Welby faces the problem of whether to tell them, since his diagnosis means it may be dangerous for Jackson to continue serving.

Episode Notes
Jackson suffered from hypoglycemia a condition in which the level of glucose in the blood is very low. The chief symptom is fatigue and lack of endurance, since the condition essentially starves the cells, particularly the energy-hungry muscle cells. Normally, higher levels of blood glucose, such as following a meal, trigger insulin release, which then signals cells to extract the glucose from the blood. (Cells that do not require as much glucose as they are triggered to receive store the excess as glycogen, a starch-like compound, or as fat.) In Jackson's particular case, a adenoma in his pancreas produced too much insulin all the time, keeping his blood sugar level too low. Removal of the growth corrected the problem. There are also cases of hypoglycemia with no identifiable cause, and it is an occasional complication of diabetes, usually caused by an incorrect dosage of injectable insulin.
