Diabetes mellitus (DM) is the body's inability to regulate the level of glucose in the blood. Glucose is the main form of sugar in the body. The body breaks down food into glucose and uses it as a source of energy. In healthy people insulin helps to regulate the glucose (sugar) levels. Insulin is a hormone produced by the pancreas (a long, thin organ located behind the stomach against the back).

In diabetics, the body does not produce enough insulin or does not use the produced insulin effectively. This results in a high level of glucose in the blood ("hyperglycaemia").

There are three main types of diabetes mellitus:

a) Type 1, earlier known as insulin dependent diabetes mellitus (IDDM) or juvenile-onset diabetes mellitus. People with this type of diabetes make little or no insulin in their body, and need regular insulin injections for survival and management of diabetes. It usually starts in childhood, but can occur at any age. This ususally happen before age of 40.

b) Type 2 (DM2), earlier known as non-insulin dependent diabetes mellitus (NIDDM) or adult-onset diabetes. This is the most common form of diabetes, and is strongly associated with genetic tendency and obesity. The body produces normal or even high levels of insulin, but certain factors make its utilization ineffective ("insulin resistance"). Sedentary lifestyle, unhealthy dietary patterns, and the consequent obesity are common causes. It usually starts in adulthood, but is beginning to be seen in obese adolescents also.

c) Gestational diabetes mellitus, or pregnancy-induced diabetes.

Gestational diabetes is raised blood glucose levels during pregnancy. It develops in 5 % of all pregnancies but usually disappears when a pregnancy is over. Women who have had gestational diabetes are at increased risk (up to 40%) for later developing type 2 diabetes

Symptoms depend on the type and duration of diabetes. Some of the signs and symptoms are related to the high blood sugar levels.

These include: Increased urination, Increased thirst, Hunger

Other common symptoms:

There may be weight loss, especially if the amount of insulin made by the body is decreasing. If insulin deficiency is marked, the person can become drowsy and then go into coma. This is called Ketoacidosis, and usually occurs in DM1. Rarely, if the diabetes is completely out of control, it can also occur in DM2. Other symptoms of ketoacidosis include: Deep rapid breathing, sometimes with a fruity odour to the breath Pain in the stomach, with nausea and vomiting.

Diabetes mellitus is diagnosed based on a high level of glucose or sugar in the blood. The doctor may suspect diabetes mellitus after taking the medical history and doing a physical examination. There are several blood sugar tests used for diagnosis:

Fasting plasma glucose test: In this test, a person is asked to fast overnight, at least 8 hours, and the level of glucose in the blood is then checked. Normal fasting plasma glucose levels are less than 110 mg/dl. A fasting plasma glucose level of more than 126 mg/dl usually indicates diabetes mellitus. A level of 110-125 mg/dl is called "impaired fasting glucose".

Post prandial (PP) plasma glucose: This is tested two hours after having a meal, which serves as a challenge for the body to regulate the blood sugar. Normal PP levels are <140 mg/dl; a glucose level of more than 200 mg/dl indicates diabetes mellitus, while a level between 140-199 mg/ dl is called "impaired glucose tolerance".

Random plasma glucose test: is that which is done at any other time. A level of 200 mg/dl or higher generally indicates the presence of diabetes.

Oral glucose challenge test (oGTT): The blood glucose is tested 2 hours after giving 75 gm glucose by mouth. This is useful for detecting borderline diabetes and a condition called "impaired glucose tolerance".

Oral glucose tolerance test: is the preferred way to diagnose pregnancy-induced diabetes. Ideally all pregnant women in India should have a blood glucose test done 30 minutes after taking 50 gm gluocse (screening test). If this is abnormal, the lady should undergo an oGTT: with 100 gm glucose (not the conventional 75 gm). Blood samples are then drawn at intervals of one hour upto 3 hours (ie at 1, 2 and 3 hours post-glucose).

Although diabetes cannot be cured, it can be controlled very successfully. The main aim of treatment of all types of diabetes is to achieve blood glucose control, blood pressure and cholesterol levels as near to normal as possible. This, together with a healthy lifestyle, will help to improve wellbeing and protect against long-term complications.

Stay Active

Being active is good for all of us but is especially important for people with diabetes. Physical activity, combined with healthy eating and medication that you may taking will help you to manage your diabetes and prevent long term complications. If you have concerns at all about becoming active, never be afraid to ask for advice.

What are the Medication

People with diabetes often need additional treatment along with making lifestyle changes such as medication to control their Blood Pressure and blood fats. Treatment is decided by your specialist. But you should be aware of timings, dosage and its function in the body.

In diabetes stopping the treatment by your own can create lots of problems.

Hypoglycemia is the common problem which can happen in pt who is being treated with oral medications or Insulin

Hypoglycemia (low blood sugar) can be life threatening condition and its very important to act early.

Low blood sugar: a level below about 60 milligrams per deciliter (mg/dl) occurs when there's too much insulin and not enough sugar (glucose) in your blood. Low blood sugar is most common among people taking insulin, but it can also occur if you're taking oral diabetes medications.

When your blood sugar is low you may feel:

Shaky or nervous, Tired, Sweaty, Hungry, Irritable, Impatient, Cold, Confused

You may also feel tingling around your mouth.

Reasons for blood sugar swings

Although it is frustrating, blood sugar levels can also be too high for no clear reason.

Sometimes these high levels may be the first sign of an infection, illness or stress.

Because blood sugar levels can go very high when you are ill, talk with your health care team about creating a sick day plan to manage your diabetes when you have a cold, flu or other illness.

Pre Diabetes

Pre diabetes is when one has higher than normal glucose level but not high enough to be diagnosed with diabetes. Pre-diabetes is present when hba1c is over 6% -6.4%.

A person with pre-diabetes can be prevented to develop Diabetes by:

1. Improving diet

2. Increasing physical activity at least 30 minutes for 5 days in a week.

3. By reducing body weight, high blood glucose levels can return to normal which reduces the likelihood of developing T2D.

Benefits of weight loss

Benefits of an active lifestyle

Maintaining a healthy weight and eating a healthy balanced diet, low in fat and rich in fiber and fruits and vegetables, as well as being physically active is an important part of managing blood sugar levels and avoiding other health complications.

Type 2 diabetes is one of the major degenerative diseases in the Western world today. It happens when your body cant use insulin properly, or cant make enough insulin. Insulin is a hormone the assists the bodys cells in utilizing glucose. It also helps the body store extra sugar in fat, liver, and muscle cells. If you dont have insulin, your body cant use the sugar in the bloodstream.

Then, your blood sugar levels get too high. High blood sugar can have a deleterious effect on many parts of your body, including heart, blood vessels, nerves, eyes, and kidneys. Those who are overweight, dont exercise enough, or have a history of type 2 diabetes in their family are more likely to get the disease. Maintaining a healthy weight, eating a healthy diet, and getting enough exercise can prevent type 2 diabetes. If you have a history of diabetes in your family, or if you are overweight, stay ahead of the disease by making healthy lifestyle choices and changing your diet.

Frequent urination is an early warning symptom of diabetes. When there is too much glucose in the blood, the kidneys work overtime to flush it out of the blood via urination. So, youll find yourself going to bathroom a lot more often than normal. There is also a bigger risk of urinary tractions in both men and women.

Individuals with diabetes have two times the likelihood of getting a urinary tract infection compared to individuals without the disease. If you find yourself getting up every couple of hours in the middle of the night, and you seem to be expelling a lot more urine than you used to, talk to your doctor and find out whether or not you have diabetes.

Increased urinary frequency is called polyuria, and individuals with diabetes are unable to regulate blood sugar levels. When too much sugars in the bloodstream, more fluids will pass through your kidneys.

The importance of insulin

Diabetes is a disease in which your body either can't produce insulin or can't properly use the insulin it produces. Insulin is a hormone produced by your pancreas.

Insulin's role is to regulate the amount of glucose (sugar) in the blood. Blood sugar must be carefully regulated to ensure that the body functions properly. Too much blood sugar can cause damage to organs, blood vessels, and nerves. Your body also needs insulin in order to use sugar for energy.

Eleven million Canadians are living with diabetes or prediabetes. Chances are, diabetes affects you or someone you know.

There are three major types of diabetes. Type 2 diabetes is the most common diagnosis, followed by type 1 diabetes. Gestational diabetes occurs during pregnancy, and is usually temporary. In addition, prediabetes is another important diagnosis that indicates an elevated risk of developing diabetes.

Type 1 diabetes is an autoimmune disease and is also known as insulin-dependent diabetes. People with type 1 diabetes aren't able to produce their own insulin (and can't regulate their blood sugar) because their body is attacking the pancreas. Roughly 10 per cent of people living with diabetes have type 1, insulin-dependent diabetes.

Type 1 diabetes generally develops in childhood or adolescence, but can also develop in adulthood. People with type 1 need to inject insulin or use an insulin pump to ensure their bodies have the right amount of insulin.

People with type 2 diabetes can't properly use the insulin made by their bodies, or their bodies aren't able to produce enough insulin. Roughly 90 per cent of people living with diabetes have type 2 diabetes.

Type 2 diabetes is most commonly developed in adulthood, although it can also occur in childhood.Type 2 diabetes can sometimes be managed with healthy eating and regular exercise alone, but may also require medications or insulin therapy.

If you think you or someone you know may have type 2 diabetes, please speak to a doctor or health-care provider.
