Alcohol can trigger either a migraine or a cluster headache. There are 3 main triggers in alcohol: Dark alcoholic beverages, such as red wine, sherry, brandy, scotch, bourbon, and beer, contain tyramine. Tyramine is an amino acid that occurs naturally in your body and is also found in many foods.
Sometimes a twin pregnancy just happens. In other cases, specific factors are at play. For example, a twin pregnancy is more likely as you get older because hormonal changes can cause more than one egg to be released at a time. Use of assisted reproductive technologies â such as in vitro fertilization â also boosts the odds of twins or other multiples.
The risk of preterm labor and premature birth are heightened when there is more than one baby in the womb. Other conditions such as preeclampsia, placental dysfunction, and TTTS are more prevalent in twin pregnancy and increase the risk of an early delivery. Research from the National Organization of Mothers of Twins Clubs (NOMOTC) indicates that about half of multiples are born before 36 weeks gestation. An informal, unscientific poll on my site indicates 18% delivered before 28 weeks and only 15% after 38 weeks.
