The symptoms develop gradually because, if you have the insulin resistant form of type 2, it takes time for the effects of insulin resistance to show up. Your body doesnât become insulin resistant (unable to use insulin properly) overnight, as you can learn about in the article on causes of type 2 diabetes.
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a form of heart disease that usually appears in adulthood. ARVC is a disorder of the myocardium, which is the muscular wall of the heart.
The disease typically develops two to four weeks after a throat infection. Signs and symptoms include fever, multiple painful joints, involuntary muscle movements, and a characteristic but uncommon non itchy rash known as erythema marginatum. The heart is involved in about half of cases. Permanent damage to the heart valves, known as rheumatic heart disease (RHD), usually only occurs after multiple attacks but may occasionally occur after a single case of ARF. The damaged valves may result in heart failure. The abnormal valves also increase the risk of the person developing atrial fibrillation and infection of the valves. Acute rheumatic fever may occur following an infection of the throat by the bacteria Streptococcus pyogenes.
