What causes an increase in serum calcium levels in chronic smokers?

Chronic smokers set up different events in their body that they are unaware of. One such event is the excessive production of calcium. This is because of the PTH-related peptide that is released into the system. The PTH-related peptide functions like PTH and cause the bones to release calcium.

At the same time, it prevents the kidneys from excreting calcium and increases absorption from the intestines. All these factors function to increase the serum calcium levels. This causes disruption of the electrolyte balance of the body. It can also interfere with the body hormones and lead to dystrophic calcification in different organs.
