Which of the following is a differential diagnosis for first trimester bleeding?

• A. Gestational diabetes
• B. Pelvic inflammatory disease
• C. Implantation bleeding
• D. Cystitis

Answer: (C)

Implantation bleeding is recognized as a differential diagnosis for first trimester bleeding because it typically occurs around the time a fertilized egg attaches to the uterine lining, which can cause light spotting or bleeding. This type of bleeding is usually light in color and is often accompanied by very mild cramping. It generally indicates a normal physiological process in early pregnancy. Other conditions listed, such as gestational diabetes, pelvic inflammatory disease, and cystitis, do not commonly present as first trimester bleeding. Gestational diabetes typically does not manifest until the second or third trimester when the pregnancy is more advanced. Pelvic inflammatory disease is often associated with more acute symptoms and may involve significant pain rather than just bleeding. Cystitis, or bladder infection, may cause urinary symptoms but is not directly related to bleeding during the early stages of pregnancy. Thus, implantation bleeding is the most relevant and precise answer related to first trimester bleeding.
