Excruciating leg cramps could signal diabetes or liver cirrhosis

Many people have experienced sudden leg cramps during sleep or exercise, causing intense pain. A Japanese doctor points out that recurrent cramps could be a sign of conditions like diabetes, liver cirrhosis, or varicose veins. He also teaches two methods—the "Heel Press Method" and "Ankle Stretch Exercise"—that can relieve and prevent severe leg cramps within 30 seconds.

According to a report by Japanese media Josei Jishin, orthopedic surgeon Dr. Kitajo Masaaki explained that the root cause of leg cramps lies in the malfunction of the muscle's "monitoring mechanism":

• Muscle spindles detect overstretching and issue contraction commands.
• Golgi tendon organs simultaneously detect overstretching and contraction, ordering the muscle to relax.
• Golgi tendon organs can age and fatigue, causing muscles to lose control and contract continuously. This compresses blood vessels, impairing blood flow and leading to muscle hypoxia (oxygen deficiency). Cells then release pain substances like prostaglandins, which are the culprits behind the severe pain of leg cramps.
• About 60 percent of cramps occur in the calf muscles, known as "anti-gravity muscles," because they easily accumulate fatigue. Coupled with their distance from the heart and poorer blood flow, this makes them prone to night cramps.

When a sudden cramp occurs, Kitajo recommends performing the "Heel Press Method":

"Heel Press Method" Steps

1. Press down on the area below the knee of the cramping leg and forcefully bend the knee.
2. Push the heel inward firmly, fully flexing the ankle.
3. Repeat the heel-pressing motion several times to stimulate the foot tendons. The calf cramp pain should ease and disappear within 30 seconds.

Daily 1-Minute "Ankle Stretch Exercise"

Additionally, Kitajo recommends the "Ankle Stretch Exercise". Doing this for one minute daily with both feet can help prevent leg cramps:

"Ankle Stretch Exercise" Steps

1. Sit on a chair and lift the leg that frequently cramps, keeping the foot off the ground.
2. Extend the ankle to its limit and hold for 5 seconds.
3. Flex the ankle to its limit and hold for 5 seconds.
4. Perform three sets for each foot.

"Ankle Stretch Exercise" Benefits

The key to this method is moving the ankle joint to the limit of its range of motion, fully stimulating the Golgi tendon organs to prevent calf cramps. It's recommended to develop a daily habit of doing this for 30 seconds per foot, totaling 1 minute for both feet.

4 Lifestyle Habits to Build a Cramp-Resistant Body

To prevent leg cramps, Kitajo suggests  four lifestyle habits to build a physique less prone to cramping:

1. Choose easy-to-turn-over bedding with moderate firmness, allowing the body to sink about 2-3cm.
2. Take a bath 1.5-2 hours before sleep, allowing body temperature to rise gently and then naturally decrease.
3. Replenish fluids and minerals after bathing; barley tea is a good option.
4. Women aged 40+ should pay attention to muscle loss and can engage in 30-minute brisk walks to promote lower limb blood circulation.

Recurrent Leg Cramps Could Indicate Serious Illness

Occasional leg cramps are rarely a major issue. However, Kitajo warns that if leg cramps occur two to three times per week or more and persist, it could be a dangerous warning sign of a serious disease:

• General causes of leg cramps: Weakened Golgi tendon organs, decreased muscle mass, electrolyte imbalance, muscle fatigue, impaired blood flow, nerve disorders.
• Serious diseases associated with leg cramps: Spinal canal stenosis, diabetes, lower limb varicose veins, liver cirrhosis.
