The three types of APS are:

Common Symptoms

  • APS I: oral thrush, diaper rash, cramping, spasms, weakness, diarrhea, nausea and vomiting, low blood pressure, and dehydration.
  • APS II: frequent urination, extreme thirst, constant hunger, weight loss, itching of the skin, changes in vision, low blood pressure, severe dehydration, enlarged thyroid gland in the neck, dull facial expression, puffiness and swelling around the eyes, and drooping eyelids.
  • APS III: puffy face, fatigue, enlarged thyroid gland in neck, puffiness and swelling around the eyes, drooping eyelids, weakness, extreme hunger, blurry vision, weight loss, shortness of breath, pins and needles sensations, patchy loss of skin color, and hair loss.
