Case


A male patient presents with a history of persistent fatigue and swelling of the neck glands, which he has experienced for several years. Additionally, he has been managing psoriasis and reports complaints of tired eyes and the presence of eye floaters. These symptoms have manifested following an Epstein-Barr virus (EBV) infection. Notably, his father has been diagnosed with retinitis pigmentosa.

Excess fructose intake and malabsorption - the consequences


Excess fructose intake and fructose malabsorption can cause gas in the colon. This gas can trigger GERD but also arrythmia. Additionally, excess fructose in the intestines causes a decrease of tryptophan absorption, which leads to decreased serotonin levels, depression and constipation.
