What causes Osteoporosis?
What causes Osteoporosis? samer kareem 7,067 Views • 3 years ago

Bone is not a static part of the body — it's constantly being resorbed (broken down) and formed throughout your life. Your entire skeleton is replaced about every decade, according to the NIH. During your childhood and teenage years, bone formation occurs more quickly than bone resorption, resulting in growth. You reach your maximum bone density and strength around age 30, after which bone resorption slowly overtakes bone formation. Osteoporosis develops when there's an abnormal imbalance between bone resorption and formation — that is, resorption occurs too quickly, or formation too slowly.

The term hypoplastic left heart syndrome (HLHS), initially proposed by Noonan and Nadas, [1] describes a spectrum of cardiac abnormalities characterized by marked hypoplasia of the left ventricle and ascending aorta. This is the same disorder characterized as hypoplasia of the aortic tract complex by Lev. [2] The aortic and mitral valves are atretic, hypoplastic, or stenotic. A patent foramen ovale or an atrial septal defect is usually present. The ventricular septum is usually intact. A large patent ductus arteriosus supplies blood to the systemic circulation. Systemic arterial desaturation may be present because of complete mixing of pulmonary and systemic venous blood in the right atrium. Coarctation of the aorta is also commonly present.

Esophageal atresia is an abnormality, or birth defect, of the esophagus that occurs early in pregnancy, as the baby is developing. The esophagus forms in the first few months of fetal life as a long, hollow, continuous tube joining the mouth to the stomach.
