Alcohol intake may be linked to the premenstrual syndrome, a new research has found. According to a pooled analysis by Spanish researchers, around one in 10 cases of PMS might be linked to alcohol intake. The premenstrual syndrome includes any or all of mood swings, tender breasts, food cravings, fatigue, irritability, and depression. Its severity varies from woman to woman. Several studies have shown that PMS tends to be more severe among women who drink alcohol, but it's not clear whether this is due to the alcohol itself or whether women reach for the bottle to cope with their symptoms. To try and find out more, the researchers, therefore, trawled research databases for relevant studies published up to May 2017 and found 19 from eight different countries, involving more than 47,000 participants.
