At a speech in Michigan on Saturday, the former First Lady, who previously rejected calls for her to run for US president, talked about her own “debilitating” menopausal issues and warned that women's lives “would be in danger” if Donald Trump returns to the White House.

Obama discussed how difficult it is for women to understand and take care of their own bodies, particularly during menstruation and menopause.

“Every month, far too many of us experience excruciating cramps and days of nausea. As we struggle through menopause, crippling hot flashes, and depression, too many women my age are unaware of what's happening to our bodies,” she added.

Michelle Obama urges men to consider women ‘more than just baby-making vessels’

Addressing the male crowd, she urged them to understand women's health concerns and regard them as “more than just baby-making vessels.”

The infringement of abortion rights, according to the former first lady, is a sign of dangerous restrictions on women's access to healthcare.

She further suggested that some men might be inclined toward voting for Trump due to their anger at the slow pace of progress, but added, “Your rage does not exist in a vacuum.”

“If we don´t get this election right, your wife, your daughter, your mother, we as women will become collateral damage to your rage,” Obama warned.
