Osteoporosis

According to the National Institute of Health, women are at higher risk of suffering osteoporosis due to the hormonal changes occurred after the menopause. Low estrogen levels and absence of menstrual periods may decrease absorption and use of calcium.
Cardiac Arrhythmia

When the heartbeats are too fast are called tachycardia and bradycardia when the heartbeats are too slow. People with arrhythmia may experience palpitations in the chest, shortness of breath, fainting and chest pain. An electrocardiogram helps to diagnose cardiac arrhythmia.
Hypertension
