A new study has found a link between alcohol consumption and premenstrual syndrome. According to the research, one out of 10 such cases are linked to alcohol intake.
Premenstrual syndrome (PMS) is a condition that affects a woman’s feelings and behaviour, symptoms of which include mood swings, bloating, breast tenderness, anger and depression. It occurs in the last half of a woman’s menstrual cycle.
Previous studies have shown that women, who drink alcohol, have more severe symptoms of PMS than who don’t. However, the reason of PMS was not clear - whether PMS is an outcome of alcohol or women consume alcohol to cope with PMS.
The team analyzed data from 19 studies from 8 different countries, involving 47,000 participants and discovered that women who were moderate drinkers, were at a 45 % greater risk of PMS and 79 % higher for heavy drinkers.
They explained that these are some possible explanations for the link found between alcohol and PMS. Alcohol might boost PMS risk by changing levels of the sex steroid hormones and gonadotropin during the menstrual cycle, or it may interfere with the production of key ‘mood’ chemicals in the brain, such as serotonin.
“These findings are important given that the worldwide prevalence of alcohol drinking among women is not negligible,” wrote the researchers.
“Based on the figures above and on our results, we estimate that 11 percent of the PMS cases may be associated with alcohol intake worldwide and 21 percent in Europe. Furthermore, heavy drinking may be associated with 4 percent of the PMS cases in the world and over nine percent in Europe,” added researchers.
According to the report, 30 % of women drink alcohol, with around 6% of heavy drinkers in the world. Whereas, women drinkers in Europe and America are almost 60 %, with over 12.5 % of heavy drinkers.
“Eliminating heavy drinking in women would then prevent one in every 12 cases in Europe,” commented the team.
The study was published in the online journal BMJ Open.
