A ligament is the tissue that connects two bones to form a joint. It's tough and fibrous, which means that when it tears, a ligament can take quite a while to heal and might even require surgery. Ligament comes from the Latin ligare meaning to bind, tie, which is precisely what a ligament does. Ligaments only connect bones to bones. Ligaments allow for range of motion. Think of how your knee or elbow is able to move up and down like a hinge. That's thanks to the ligaments connecting the bones to form knee and elbow joints.
Cramping is one of the most common symptoms a woman experiences before, during or after her menstrual cycle. Caffeine contributes to cramps because of its diuretic nature--it increases urine production and promotes dehydration. In addition, coffee contains oils that may inflame your intestines and cause cramping. Fibrocystic breast syndrome is a condition that many women suffer before or during a menstrual period.
Too much caffeine may also promote headaches, migraines and high blood pressure in some individuals (55, 56). In addition, caffeine can easily cross the placenta, which can increase the risk of miscarriage or low birth weight. Pregnant women should limit their intake (55, 57, 58). Finally, it's worth noting that caffeine can interact with some medications. Individuals taking the muscle relaxant Zanaflex or the antidepressant Luvox should avoid caffeine because these drugs can increase its effects . Bottom Line: Caffeine can have negative side effects in some people, including anxiety, restlessness and trouble sleeping.
