Can Purging Cause Pneumonia And Hypercalcemia?
Possibly
Detailed Answer:
If while purging you accidentally get food down your windpipe in quantities not large enough to choke you, it can cause pneumonia.
Regarding hypercalcemia, if blood samples are drawn after food, there is a chance of blood levels of calcium appearing higher than normal. Being dehydrated can further increase the chances of hypercalcemia. So if you have binged and purged to a significant degree, it is possible to see higher than normal levels of calcium in the blood.
However, this requires a thorough evaluation by an endocrinologist in person who will examine you in detail before running tests like
CBC
Electrolytes
Creatinine
SGOT
SGPT
Albumin
TSH
Free T4
HbA1c
Ionized calcium
Phosphorus
Intact PTH
25 hydroxy Vitamin D
