Answer: This is TRUE for me. Osteoporosis is a preventable disease.
Explanation:
In this condition, bone density ( the amount of bone tissue) is reduced because it's deposition does not keep pace with resorption. Although the bone is adequately mineralised, it is fragile and microscopically abnormal, with loss of internal structure.
Peak bone mass occurs around 35 years and then gradually declines in both sexes. Lowered oestrogen levels after the menopause are associated with a period of accelerated bone loss in women. Thereafter bone density in women is less than in men for any given age. That is why in North America, one-third of all women experience fractures because of this disease, amounting to about 2 million bone fractures per year.
Common features of osteoporosis are:
--> skeletal deformity: gradual loss of height with age, caused by compression of vertebrae.
--> bone pain
--> fractures: especially of the hip ( neck of femur), wrist and vertebrae.
It is TRUE for me that some risk factors can't be changed ( which is the low oestrogen levels that occur after menopause in women) but others, such as poor calcium intake, can.
Exercise and Calcium intake during childhood and adolescence are important in determining eventual bone mass of an individual and in preventing risk of osteoporosis in later life.
Explanation:
After a physical examination of the child, some of the manifestations that lead the pediatrician or doctor to conclude that the child has had moderate dehydration are the following:
Sunken eyes and in case he is crying, the cry is without tears, dry oral mucosa, and recapillary time greater than 2 seconds.
Answer:
Cause of male infertility are:
- Abnormal sperm production or improper functioning because of undescended testicles
- Genetic conditions like Klinefelter syndrome
- Health problems such as diabetes or infections such as chlamydia, gonorrhea, mumps & HIV
- Enlargement of testes veins also result in low sperm count
Low sperm count symptoms are:
- Problem with sex activity - low sex drive or difficulty in maintaining the erection eg.Erectile dysfunction
- Pain or lump in the testicle area
- Decreased facial or body hair or other symptoms of chromosomal or hormonal disorders
<u>Klinefelter syndrome :</u>
It is a genetic problem in which a male is born with supplemental copy of X chromosome. It usually occurs as a consequence of genetic purposeless error after the conception.
Signs & symptoms include:
- Taller than average stature
- Absent, delayed or incomplete puberty
- Small & firm testicles
- Small penis
- Enlarge breasts ( gynecomastia)
- Long legs, short torso & broader hips in comparison with other teens
Treatment of low sperm count include:
- Surgery: A varicocele can be corrected surgically or vas deferens can be repaired
- Treatment for sexual intercourse problems
- Hormone therapy & medications
- Assisted reproductive technology
- Treating infections
