There is no evidence that drugs for pelvic inflammatory disease affect the level of HCG in the blood. The drugs used to treat pelvic inflammatory disease are usually antibiotics such as cephalosporins and erythromycin, which mainly play the role of anti-inflammatory and anti-infection. HCG is a glycoprotein secreted by the placenta, and the secretion of estrogen and progesterone in the female endocrine system is the main factor affecting the level of hcg in the blood. Especially in early pregnancy, the activity of the secretion system in the body is enhanced and gonadal hormones are released in a pulsatile manner, which leads to intermittent elevation of hcg. In different periods of pregnancy, due to the differences in the physical constitution of pregnant women, their own HCG values will also undergo greater changes, resulting in more fluctuating factors, in addition to pregnancy, tumor diseases, teratomas and so on may also affect the HCG content. The drugs used to treat pelvic inflammatory disease are not hormonal drugs, so they will not have an effect on the level of HCG in the blood. In addition, the drugs all need to be used under the guidance of a doctor, not self-medication.
