Dehydration One of the most prevalent causes of leg cramps is dehydration. A cramp is an involuntary muscular contraction. Your body's fluids help your muscles to relax, but when they are dehydrated, they become irritable and prone to cramping. As fluid levels drop, the muscle fibers begin to tense up and may even experience premature separation from the bone.
How does dehydration cause leg cramps? When you lose water through sweating or breathing, the body compensates by pulling extra water out of other areas, such as the muscles. These water withdrawals cause the muscle tissue to become drier than it should be, which can lead to cramping. People who exercise heavily in hot climates are especially at risk because they tend to lose more water through sweat.
If you're drinking enough water but still experiencing leg cramps, it could be caused by other factors as well. For example, certain medications and chemicals found in some foods and beverages can cause muscle spasms or trigger existing cramps. You doctor may also have you limit your consumption of certain fruits, which contain high concentrations of potassium. Too much potassium can cause muscle problems including cramping.
Finally, not exercising what body parts enough? If you don't use your legs-especially if you sit all day-they will cramp up. The same goes for arms and chest muscles. Use them or lose them!
Some cramps are caused by misuse of your muscles. This usually happens while you're exercising. Cramps can also be caused by muscle injury and dehydration. The excessive loss of fluids in the body is referred to as dehydration. Muscle injuries occur when a muscle is strained or torn. They can also happen when a small bone in the muscle breaks. These injuries need to be treated by a doctor.
Exercise-related cramping is more common among new exercisers. This is because it takes time before your body gets used to the stresses of training and competing. At first, you will likely suffer from some muscle soreness after each workout. This is normal. As you continue with your workouts, they will become easier and less painful.
For most people, cramping affects only one muscle group at a time. You may experience leg cramps due to lack of water intake, fatigue, certain medical conditions, or taking drugs. These can be reduced by changing your posture, wearing comfortable shoes, getting enough sleep, and controlling your diet. If these measures fail, see your physician for advice.
Muscle cramping is very painful and should not be ignored. It is important to identify the cause of the cramp and take appropriate action.
Leg cramps can also be caused by changes in the chemical composition of the blood. Cramps can be caused by a lack of potassium, calcium, magnesium, or an excess of bicarbonate. Cramps when walking and at night are caused by a lack of oxygen in the blood (as occurs during exercise), shallow breathing, and lung illnesses. These factors also affect how much oxygen is delivered to other parts of the body including the brain. Poor oxygenation of the blood to various tissues leads to pain, allodynia, and muscle spasms.
The most common type of leg cramp is called "compression" because the muscle is trapped between two bones or hard objects. This type of cramping usually happens while sitting or standing and often goes away on its own after a few minutes. It may be caused by tight clothing, especially shoes without enough room for the toes, or lying on the stomach with the legs bent. Compression leg cramps can be treated by removing the source of the problem, such as taking off tight clothes or shoes, moving about to avoid lying on the stomach, and stretching muscles before sleep. A low dose of a medication called levodopa/carbidopa may help prevent compression cramps by keeping dopamine levels high in the body. Dopamine is one of several chemicals that transmit nerve signals within the brain and spinal cord.
Another type of leg cramp is called "laxity" because it involves loose, shaking muscles.
Muscle cramps can be caused by overuse of a muscle, dehydration, muscle tension, or just maintaining a position for an extended amount of time. However, in many situations, the cause remains unknown. Although the majority of muscular cramps are innocuous, some may be caused by an underlying medical issue, such as a lack of blood flow. This could be due to arterial blockage from cholesterol buildup or venous thrombosis (clot formation). Other conditions that can lead to cramping include hypoglycemia (low blood sugar), hyperthyroidism (overactive thyroid gland), and kidney disease.
Leg cramps can be severe enough to cause pain and discomfort and prevent us from moving our legs. They often occur at night when we are lying down and can last for several hours. In fact, these cramps are called "nocturnal leg cramps" and are more common among older adults. Young children, pregnant women, and people with diabetes frequently experience leg cramps as well.
