A 29-year-old female presented to the clinic with the chief complaint of recurrent, intensely itchy rashes in the armpit and perianal regions. The rashes had been present intermittently for approximately 1 year and were characterized by redness, irritation, and itching. She had previously been evaluated by her OB-GYN and was prescribed a topical antifungal cream, which provided temporary relief but did not fully resolve the condition. The rash would improve while using the medication, but returned shortly after discontinuation.
Recurrent candidiasis is a common condition, with chronic stress and reduced antioxidant capacity identified as key predisposing factors. Studies show that women with recurrent candida infections demonstrate significantly blunted morning cortisol levels compared to controls (p<0.002), indicating signs of chronic stress, and stress is considered the primary cause of candidiasis.
During the intake, the patient reported that the onset of the rashes coincided with a particularly stressful period in her life. In the previous year, her grandmother had been dying from cancer. During this time, the patient began experiencing recurrent strep throat infections and was prescribed antibiotics multiple times, estimating 4-5 courses over that year (approximately one course every 2-3 months).
Antibiotic use is a well-established risk factor for Candida overgrowth. Studies show that antibiotics significantly alter the microbiome, transforming the gut from a niche that restrains Candida to one that promotes invasive growth. Additionally, antibiotic treatment increases carbohydrates, sugar alcohols, and primary bile acids, all of which promote candida growth, while decreasing carboxylic acids and secondary bile acids that normally inhibit it.
Shortly after this period of repeated antibiotic use, she began noticing several gastrointestinal symptoms that were not previously present. These included significant bloating, malodorous gas, episodic nausea, and irregular bowel movements. Her stools alternated between constipation and watery diarrhea, and she frequently noticed mucus in the stool. She also reported increasing anxiety and stress during this time, along with notable sugar cravings and gradual weight gain.
The patient attempted several dietary and supplemental interventions before. She had tried eliminating both gluten and dairy, which provided minimal benefit. She also experimented with various probiotics and herbal teas to support digestion. While some of these measures provided mild or temporary improvement, none resulted in sustained resolution of her symptoms.
Physical observation during the visit revealed a thick white coating on the tongue that did not easily scrape off. This finding is often associated with yeast overgrowth or gastrointestinal dysbiosis. Combined with the patient’s symptom presentation and history of repeated antibiotic exposure, the clinical picture suggested possible intestinal Candida overgrowth contributing to both her digestive symptoms and recurrent skin rash.
