After the coach’s discriminatory decision, the player realized that if he turned down the “medical redshirt” offer, his playing time would have been very limited and not worth the “pain and effort of practice. He was asymptomatic when he attended a “job fair” on the campus of a state university where he had his glucose checked and with a reading of 270 mg/dL (15 mmol/L) diabetes was diagnosed. He was referred to the campus diabetes center, where he was seen only by a physician extender, and based on a positive C-peptide reading, he was told that he had type 2 diabetes and was started on metformin. In this case, the clinical history should have been enough to suspect type 1 diabetes. Utilizing a C-peptide level to distinguish between type 1 and type 2 diabetes may not always be appropriate because during the early 4 phase of type 1 diabetes, the C-peptide level is often normal. This is especially true when high glucose levels are reversed irrespective of the method that is utilized to lower the glucose. This occurs because relieving “glucotoxicity” results in increased insulin sensitivity and improved endogenous insulin release. In addition, ~10% of patients with type 1 diabetes permanently retain endogenous insulin production. Appropriate utilization of laboratory tests should confirm and not contradict the clinical impression. Growth and sexual maturation in children with insulin-dependent diabetes mellitus.

The patient noted intermittent symptoms of palpitations, difficulty concentrating, and diaphoresis lasting several hours once or twice a week. For days following the spells she had anorexia and lost 15 lb during the course of a year. Her primary care physician completed an extensive spell workup before referral to endocrinology and no clear cause was identified. A spell can be defined as a “sudden onset of a symptom or symptoms that are recurrent, self-limited, and stereotypic in nature. The reason it was ordered is unclear, but the results were surprising in this patient without a known history of diabetes. Antiglutamic acid decarboxylase, anti-insulin, and anti-islet cell antibodies were negative. As she is likely early in the course of her disease, further data and time should allow for proper classification. At the time of endocrinology consultation, a thorough medical history was obtained. Her past medical history was significant for degenerative disk disease and a hysterectomy and bilateral oophorectomy 10 years ago. The patient confirmed postprandial hyperglycemia and reported several self-monitored blood glucose readings >200 mg/dL (11. She noted that her postprandial hyperglycemia occurred only after eating high-carbohydrate foods. She reported symptoms of palpitations, diaphoresis, weakness, and difficulty concentrating associated with the hyperglycemia. We hypothesized that the patient’s symptoms were due to an exaggerated physical response to fluctuating blood glucose. Adrenergic symptoms have been noted in patients with elevated blood glucose that rapidly 3 decline to normal, sometimes termed relative hypoglycemia Furthermore, studies have demonstrated decreased energy and reduced cognitive function during hyperglycemic episodes in patients with type 2 4 diabetes. Fluctuating blood sugars in the absence of hypoglycemia is not a common consideration in the differential diagnosis of a spell, but given that other causes had been ruled out, this seemed to best explain the patient’s subjective complaints and objective findings. The patient was asked to monitor her blood glucose closely while taking this medication. She had two symptomatic hypoglycemic episodes about 4 h after taking the medication and self-discontinued repaglinide. She continued to have spells during the day, but noted if she skipped breakfast and lunch, she no longer had symptoms. For 1 month, she ate only one meal in the evening, resulting in the resolution of her spells but an additional 10 lb weight loss. She then developed symptomatic fasting hypoglycemia (self-monitoring) with resolution of her symptoms after drinking juice. This patient meets criteria for suspicion of Whipple’s triad (symptoms of hypoglycemia, documented hypoglycemia, resolution of symptoms with oral intake). Results were not consistent with endogenous hyperinsulinemia or surreptitious insulin use. A computed tomography scan of the abdomen and pelvis was performed, and no abnormalities were noted (no evidence of a parenchymal tumor). After this extensive negative workup, we concluded that her hypoglycemia was due to malnourishment. This diagnosis was consistent with her elevated β- hydroxybutyrate level during the fast and the limited glucose response to glucagon. We prescribed acarbose (25 mg) before lunch and dinner to reduce postprandial fluctuations. Since starting this medication, she has been eating three meals regularly without experiencing recurrent spell symptoms. Our patient may have the beginning stages of antibody-negative type 1 diabetes of adulthood. She is extremely sensitive to blood glucose fluctuations, and her spells were due to rapid increase and then decrease of her blood glucose levels following high-carbohydrate meals. Because of the severity of her symptoms, she limited her oral intake and eventually developed hypoglycemia associated with malnutrition. By prescribing acarbose, we were able to reduce her symptomatic postprandial fluctuations and allow her to eat regular meals.
