Atopy, Food Hypersensitivities, and Obesity





A Case Study Submitted By Scott Rigden, MD




Clinical Case Study on Atopy, Food Hypersensitivities, and Obesity

When she came to our office, Ursula* had an extensive medical history of severe allergies, eczema, asthma, folliculitis, and dry skin since birth, in addition to being overweight. She also had battled hypoglycemia for many years. Allergy work-ups showed numerous inhalant allergies, which required monthly allergy injections. She knew she had food allergies to soy and peanuts, and she was allergic to penicillin. Ursula had tried to lose weight many times, including following commercial weight-loss programs, self-directed regimens, and working with a personal trainer, but with no success. At the time of her first appointment she was working out with weights three times a week for a total of 120 minutes, combined with a rigidly disciplined 1400 calorie diet, and she had not been able to lose weight. Medications included Estrace 0.5 mg daily. She had had a total hysterectomy and tonsillectomy in the past.

Ursula’s physical examination was very positive for allergic nasal mucosa, allergic shiners around the eyes, mild wheezing bilaterally, and eczema on the hands, forearms, and posterior scalp. Extensive dermatitis and folliculitis were noted on the face and legs.

1.       Initiate a 1300-1400 calorie, low-glycemic-load diet, with five to six small feedings per day. Also eliminate eleven foods including egg, milk corn and wheat which showed very high reactions in her RAST IgG test. Every morning, have two scoops of a hypo-allergenic rice-based protein powder.

2.       Keep careful daily records of food intake and symptoms.
