Recently tested positive for gastric parietal cells - can gut issues cause hair loss?

Hello and thank you for your question. If you have not already done so, I suggest a full blood panel be done to see exactly what is going on before you do anything else. There are lots of possibilities of what could be causing your hair loss. Best of luck to you.

Since the screening test for antibodies against gastric parietal cells is a diagnostic tool for chronic autoimmune gastritis, which could be the cause of pernicious anemia, it's important to consider. Any type of anemia can lead to hair loss, as it affects the ability of red blood cells to carry oxygen needed to nourish the hair follicles. Additionally, long COVID can also result in telogen effluvium, another form of hair loss. Therefore, I recommend getting blood work done to check for anemia, serum vitamin B12, serum vitamin B1, serum total vitamin D, TSH, serum ferritin, ESR, and ANA levels to rule out any correctable causes of hair loss.
