Final answer:
Anorexic patients can develop osteopenia due to the lack of proper nutrition and weight-bearing activities. A child should be able to sit up independently around 6 to 7 months of age. Metrorrhagia is the term used to describe irregular bleeding or bleeding between menstrual periods.
Step-by-step explanation:
Anorexic patients can develop osteopenia, which is a condition characterized by low bone mineral density. This is due to the lack of proper nutrition and weight-bearing activities, as well as hormonal changes associated with anorexia nervosa. Without adequate nutrients like calcium and vitamin D, bone formation and maintenance are compromised, leading to weakened bones.
A child should be able to sit up independently by around 6 to 7 months of age. This milestone is achieved as a result of the development of core strength and muscle control in the back and abdominal muscles.
Metrorrhagia refers to irregular bleeding or bleeding between menstrual periods. It can be caused by various factors such as hormonal imbalances, certain medications, uterine abnormalities, or underlying medical conditions. It is important for individuals experiencing metrorrhagia to consult a healthcare professional for proper evaluation and management.
