Gout is an inflammatory disease affecting the joints , commonly the big toe of the foot, the mid foot or the ankle. This is caused by an increased level of uric acid in the blood. Purines break down inside the body to form uric acid. When there is too much of purine intake or when there is less of excretion of uric acid by the kidneys, it leads to an increase in the body.

A lot of people are affected by this and often are mistaken for having fractures and land up having X-rays taken. The pain is excruciating and can make life miserable to a point where common chores such as walking, standing, driving are so much limited.

Hyperuricemia ( high levels of uric acid) are associated with the following:
kidney stones

 

 

 

• Abdominal obesity
• Associated with diabetes mellitus type 2
• Associated with metabolic syndrome
• Joint destruction with recurrent attacks
• Stones in the urinary system- these cannot be seen in normal X-Rays as it does not block the X -rays. Uric acid stones are smooth rounded and so may not cause blood in urine.

• Generally males are affected more. Women after menopause can be affected.

• Chronic inflammation leading on to joint destruction and change in bone shape. This can lead to Tophi ( pronounced as TOE-fi)

• Consume the gout friendly food
• Maintain a healthy lifestyle and prevent being overweight or obese.

How to treat:

Ice cubes to be used for fomentation of the affected areas.
• Pain killers such as Indomethacin or Naproxen or Sulindac are preferred. However noted pain killers such as Ibuprofen ( Cataflam®) or diclofenac ( voltaren®) will not always be effective.

Oral Steroids ( prednisolone) in high doses can be used to reduce the inflammation. Some need an injection of steroids into the joints to relieve the pain.
• After the acute attack is subsided, allopurinol can be used to prevent the flares. Taking this during an acute attack may cause worsening of the attack.
• Sometimes Probenecid is advised by the doctor along with the other medicines to help in excretion of uric acid.
