3. Osteoporosis

Osteoporosis is an age dependent disorder with loss of the normal density of bone. The bones become fragile and are easily fractured. Bones that are affected by osteoporosis can fracture with only a minor fall or injury. Elderly men and women are most susceptible because of hormonal changes which occur with advancing age.

Symptoms

  1. The persons suffering from osteoporosis may not know about their condition for a long time, because osteoporosis doesn’t cause clear cut symptoms and one may not realize till a bone fracture.
  2. The symptoms of osteoporosis are related to the location of the fracture.
  3. Fractures of the spine can cause severe ‘band like’ pain that radiates around from the back to the side of the body. Repeated spine fractures can cause chronic lower back pain, as well as curving of the spine, which gives the individual a hunched-back appearance.
  4. Some patients with osteoporosis develop stress fractures of the feet while walking or stepping off. Hip fractures typically occur as a result of a fall. With osteoporosis, hip fractures can occur upon even minor accidents. Hip fractures may take a very long time to heal because of poor bone quality. 

Treatment

  1. Patients suffering from osteoporosis are generally treated with vitamin D and calcium supplements. In addition they are advised bed rest so that the condition does not worsen.
  2. Changes to lifestyle and diet are also recommended. The patients are advised to take calcium either via dietary means or via supplements in the form of tablets. Since body absorbs about 500 mg calcium at a given time, the calcium intake should be spread throughout the day.
  3. Exercise also helps to protect persons from the risk of getting osteoporosis. However, it is important to do exercises for osteoporosis under the guidance of a professional physiotherapist.

4. Cancer

It is the uncontrolled and unwanted growth of cells.

Causes

  1. No definite cause has been arrived at so far. However, it is found that body has proto-oncogenes. These are activated by some substances or stimulus, which convert these into active cancer-causing oncogenes.
  2. Heavy smoking and alcoholism.
  3. Chewing of tobacco.
  4. Consistent irritation of skin or repeated injury at the same point.

Cancer is a kind of tumorous growth. Tumours can be classified into two categories:

(a) Benign tumour

It remains confined to the place of origin and does not spread to other body parts. It is relatively harmless.

(b) Malignant tumour

It spreads to other parts of the body and growth is rapid. This is serious and may cause death of the patient.

Symptoms

  1. Persistent lump or thickening in tissues, specially in tongue, breast and uterus.
  2. Any irregular bleeding or blood-tinged discharge from any body opening.
  3. Any sore that does not heal quickly.
  4. Change in the form of mole or wart.
  5. Persistent hoarseness in voice, cough or difficulty in swallowing.

Prevention and cure
