Guys please go for celiac disease tests. I can not say it is the cause or the effect of PFS but for many of us, celiac disease is now a fact. Oat meal twice caused me to call 911, second time in critical condition. Just Google and you will find many ex Accutane users are now celiac patients. celiac disease and low tetosterone go together.
SYMPTOMS
diarrhea or constipation, weight loss or gain, abdominal pain and bloating, malnutrition, muscle weakness, anemia, depression, edema in the lower limbs from poor protein assimilation, and poor concentration. In children, there is also the inability to grow/thrive, poor tooth and bone development accompanied by tooth decay, and a distended and very sensitive belly.
Note:
if in the past you came negative for celiac that does not mean you are free. I just read few cases where celiac was postive on 2nd or 3rd tests. Symptoms come first but clinical diagnosis takes time.
