Eating too much ice cream will not cause delayed menstruation. Excessive consumption of ice cream may cause gastrointestinal disorders, causing intestinal cramps, stomach cramps, stomach pain, and in severe cases, diarrhea. Excessive consumption of ice cream may cause a transient decrease in body temperature. Ice cream can only irritate the gastrointestinal mucosa or cause a drop in body temperature, not a delay in menstruation. A common clinical cause of delayed menstruation is pregnancy, which can cause delayed menstruation. In case of ovarian dysfunction, stress, exertion, or environmental changes, it may cause a delay in menstruation.
