Diabetes can be screened using an HbA1C level, fasting plasma glucose, or an Oral Glucose Tolerance Test (OGTT). If fasting plasma glucose is used alone for screening, ≥ 2 abnormal readings are required to make the diagnosis. An HbA1C level…
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterised by insulin resistance and impaired insulin secretion leading to hyperglycaemia. It peaks between 60 and 70 years and is more common in men. Screening for type 2 diabetes Diagnosis…
Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease caused by the destruction of insulin-producing pancreatic beta cells. This results in absolute insulin deficiency and hyperglycaemia. It commonly presents in childhood and adolescence with the triad of polyuria, polydipsia…
Systemic sclerosis is a chronic autoimmune connective tissue disease characterised by skin fibrosis (scleroderma), fibrosis of the internal organs, vasculopathy, and immune system dysregulation. It is more common in women and peaks between 60 and 70 years. Classification Classification Description…
