Diabetes is a condition where a person either does not produce required amounts of insulin or is unable to utilise insulin appropriately. It is a common (about 10% of the population), complex disease. It can cause complications if not treated and controlled well.
Types of Diabetes:
There are 2 common types of diabetes Type I and Type II. There are other rare varieties due to pancreatic diseases, hormonal disorders, in pregnancy, after drugs and even rarer genetic disorders.
Type I is the cause in about 10 % of cases, onset is in childhood or young age and insulin is required for treatment.
Type II is the common variety, onset is usually around 50 Yrs of age, often associated with overweight and the risk is high if one parent is diabetic (30 %) and if both parents are diabetic (50 %). During initial stages, diet modification and oral drugs may control sugars but later insulin may be required.
Classically symptoms in diabetes are polyuria (more urine), polydypsia (more thirst ) and polyphagia ( more eating). In children very high sugars may develop suddenly and patient may become unconscious at the onset (DKA etc). Infections both recurrent and difficult to treat may occur. However in a large no the disease remains without many symptoms and found out accidentally or when complecations arise.
Signs are seen only in advanced and long standing diseases. These are few and may include eye, heart, nerve changes, dehydration and very rapid breathing due to acid accumulation in the body.
Diagnosis of diabetes:
Diabetes is diagnosed by blood glucose testing or glycated hemoglobin levels.
Normal Plasma glucose level after 8 hrs of fasting is < 100 mg/dl. Normal 2 hrs after breakfast (called PP) or after 75 gms of glucose orally is <140 mg. Diabetes is diagnosed if either fasting plasma glucose is >126 or PP or oral GTT (after 75 gms of glucose is >200 mg/dl.
If fasting value is 100 -125 it is called impaired fasting glucose and if PP or Oral GTT is between 140 and 199 mg/dl it is called impaired glucose tolerance( IGT).
In a person with symptoms of diabetes a random value of plasma sugar >200 mg /dl or fasing plasma sugar >126 mg/dl qualifies for diagnosis of diabetes.
Lab tests for diabetes
For common types of diabetes the following tests may be required at the time of initial diagnosis.
Complete blood counts, Blood sugar, kidney and liver function tests, urine routine and urine for microalbumin, lipid profile, Chest X Ray, ECG. Ultrasonography of abdomen, fundus examination, foot examination and blood pressure is noted.
In Type I cases or where genetic, pancreatic or hormonal disorders are suspected, tests for these are carried out as appropriate.
This is a chronic disease and lifelong follow up and treatment are required.
For patients suffering from type II /adult onset diabetes :In type II diabetes, diagnosis is often late (after the disease has already been present for some time). In early days T2DM (short for the adult type of diabetes) are often without symptoms. Hence the delay in diagnosis. This means complications will be seen early after diagnosis. Foot Care :
Foot disease in diabetes may lead to difficulty in walking, pain and may lead to infections. If neglected amputation may be required.
Inspect feet with a mirror before going to sleep every night.
Use well fitting shoewear.
Do not walk bare feet even in the house.
Socks should be clean and correct size.
In case of deformities of feet, special shoes can be worn. Eye Care :
It is nowadays the commonest cause of blindness throughout the world. Continue Reading ~ Second Medical Opinion / Advice
Nephrotic Syndrome Kidneys receive approximately 1 liter of blood every minute. Of this, about 100 ml gets filtered in the kidney. This contains, small molecules and few large molecules. This is due to the intricate cellular structure that prevents proteins from getting filtered into the urinary space. A derangement of this filter results in passage of heavy amounts of proteins in urine. This condition is called HeavyProteinuria or Nephrotic syndrome or Nephrosis. Definition:
In the urine, the protein excretion is > 3.5 gm/day or in children, it is >50mg/kg of body weight. In most cases, the serum albumin is <3gm/dl (normal>4), and passage of lipids in the urine. The lipids in the blood increase and swelling of face and feet also occur. Causes of Nephrotic Syndrome:
In children, most cases are due to Minimal Change Disease, FSGS, MPGN etc. In adults, most cases are due to primary illness while upto 30% may be due to secondary illness. Clinical Features:
Apart from Edema, ther…
Asthma or Bronchial Asthma is a common disease. About 75 % cases start in childhood before 10 years of age. A large no of patients stop having symptoms at the time of puberty and some may again have the disease in the later years. It is uncommon after 50 years of age. It can be troublesome, disabling and if not treated properly may be dangerous.
The disease results from heightened reactivity of the airways in response to irritants, allergens, fumes and at times exercise. It is typically intermittent and a person feels well when there is no ongoing attack of asthma. Symptoms:
Symptoms of asthma are shortness of breath, difficulty in breathing, cough and whistling sounds during breathing. These symptoms may also be seen in a no of heart, lung or infective conditions. Hence the diagnosis is usually made by experienced doctors after a few episodes have occurred!
The important markers of the disease are rapid reversibility of the signs and symptoms with appropriate treatment or spontaneousl…
