Osteoporosis is a disease that weakens your bones. Osteoporosis is not painful but it makes your bones more prone to breaking (fracture). Women are more likely than men to suffer from osteoporosis and as you get older you are more likely to have it. Tests Osteoporosis can be diagnosed by measuring bone mineral density (BMD). This test involves taking x-rays or a computer tomography (CT) scan of the bones in your spine, wrist, arm or leg. You may be asked to have a blood test to look for reasons why you might have osteoporosis. Treatment There is no cure for osteoporosis, but there are treatments that can improve bone strength and reduce your chances of breaking a bone. If you are diagnosed with osteoporosis you may be prescribed several medications to improve your bone strength. You will have follow-up either with your GP or specialist to make sure that the medication suits you. You will be given some more detailed reading about things you can do to help manage your osteoporosis and about the type of medication you are on.

The thyroid is a gland that sits in the front, and towards the bottom of, your neck. It is responsible for producing a hormone called thyroxine. Thyroxine has an important role in the body as it affects many organs including the heart, muscles and bones. Diseases that affect the thyroid can make it either overactive (producing too much thyroxine), underactive (not producing enough thyroxine) or enlarged (goitre). Endocrinologists specialise in these diseases as well as cancer of the thyroid. Tests Thyroid problems are usually picked up with a blood test but there are other tests you may have to work out why the problem has occurred. These include: an ultrasound scan. This is where a hand-held scanner head is passed over your thyroid gland and pictures are taken a nuclear medicine scan. This is where you are given something to drink that contains a substance that only goes to the thyroid gland. Although it is radioactive it does not damage you or anyone else. Pictures are then taken of the thyroid gland that give the doctor information about what might be causing the problem fine needle aspirate (FNA). This is where the doctor puts a very fine needle (smaller than for a blood test) into the thyroid gland to take some cells to look at under the microscope.

The pituitary gland is in your brain. It controls most of the endocrine (hormone) system in your body. When disorders occur in this gland a variety of problems can appear. If your doctor thinks you have problems in this area (usually discovered with a series of blood tests) they will refer you to a specialist endocrinologist.

Polycystic ovary syndrome (PCOS) is a hormonal disorder that can cause you to have a variety of symptoms including: no periods or irregular periods, increased hair growth on the face and body, acne (pimples) and increased bodyweight. PCOS is also one of the main causes of infertility in women. The ovaries of women with PCOS often contain many small cysts (fluid-filled sacs), but this does not seem to be the cause of the condition. For women who have not reached menopause, the most common treatment is the birth control pill, which will regulate your periods. There are also other medicines that can help control the symptoms.
