Can endocrine disorders cause two lines to appear on a pregnancy test stick?
Disease description:
Recently, I used a pregnancy test strip and surprisingly saw two lines appear. I think it might be due to recent hormonal imbalance. I would like to ask, can hormonal imbalance cause two lines to appear on a pregnancy test strip?

Endocrine disorders generally do not cause a pregnancy test stick to display two lines.
Endocrine disorders may lead to hormonal imbalances in the body, especially changes in estrogen and progesterone levels. In some cases, such imbalances might result in a false-positive reaction, causing two lines to appear on a pregnancy test strip. However, pregnancy test sticks primarily detect the level of human chorionic gonadotropin (hCG) in urine to determine pregnancy status. hCG is a hormone produced by the placenta after pregnancy, and its levels are extremely low in non-pregnant individuals. Hormonal imbalances may affect the menstrual cycle, causing ovulation abnormalities or interfering with embryo implantation. However, once fertilization occurs and the embryo starts secreting hCG, the pregnancy test will show a positive result (two lines). Nevertheless, a false-positive result could also be caused by other factors, such as endocrine disorders.
Therefore, if a pregnancy test displays two lines, it may indicate pregnancy, but it is also recommended to undergo further medical examination to confirm the situation. Additionally, if you suspect you have symptoms of an endocrine disorder, you should seek medical advice promptly for evaluation and treatment.
