Like can keep eating and eating (get about an hour after meals where I feel satisfied/non-hungry and then I get slightly peck-ish soon after that and completely starving and almost shaky 4-5 hours after, regardless of what I eat.
Only two medical things that I can think of is I have IBS-D (fairly mild, get slightly watery but solid-ish stools so maybe less nutrient absorption) and low blood pressure (heard it can trigger the appetite control centre in the brain as the body wrongly thinks it needs more energy/food).
I have been tested for diabetes and don't have it.
I am mid-20s, female.
