Recently I have been having nausea and don t have much of an appetite although I eat, and I am now pooping and peeing white chunks. I also have noticed an increase in how much the blood vessels in my eyes are more noticeable.I have an immune and cardiovascular system disorder so I usually don t worry when I feel a little weak, foggy, or fatigued, although those symptoms have been more evident. I am 20 years old, female, 5 11, and I weigh around 158 pounds.
