Is loss of sense of hunger during menstrual cycle normal and what could cause this?

Yes, loss of appetite during the menstrual cycle can be normal for some individuals due to hormonal fluctuations, particularly changes in estrogen and progesterone levels. These hormonal shifts can affect mood and energy levels, leading to decreased hunger. Additionally, physical symptoms like bloating, cramps, or nausea can also contribute to a reduced desire to eat. If the loss of appetite is significant or prolonged, it may be helpful to consult a healthcare professional.
