Glucose (blood sugar) levels
Both low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia) are of concern for patients who take insulin. It is important, therefore, to carefully monitor blood glucose levels. In general, patients with type 1 diabetes need to take readings four or more times a day. Patients should aim for the following measurements:
Pre-meal glucose levels of 90 - 130 mg/dl
Bedtime levels of 110 - 150 mg/dl
Different goals may be required for specific individuals, including pregnant women, very old and very young people, and those with accompanying serious medical conditions.
Finger-prick test. A typical blood sugar test includes the following:
A drop of blood is obtained by pricking the finger.
The blood is then applied to a chemically treated strip.
Monitors read and provide results.
Home monitors are about 10 - 15% less accurate than laboratory monitors, and many do not meet the standards of the american diabetes association. Most doctors believe, however, that they are accurate enough to indicate when blood sugar is too low.
To monitor the amount of glucose within the blood a person with diabetes should test their blood regularly. The procedure is quite simple and can often be done at home.
Some simple procedures may improve accuracy:
Testing the meter once a month.
Recalibrating it whenever a new packet of strips is used.
Using fresh strips; outdated strips may not provide accurate results.
Keeping the meter clean.
Periodically comparing the meter results with the results from a laboratory.
Supplementary monitoring devices. Other devices are available for monitoring blood glucose. These devices are used in addition to traditional fingerstick test kits, and glucose meters but do not replace them:
Continuous glucose monitoring systems (cgms) use a needle-like sensor inserted under the skin of the abdomen to monitor glucose levels every 5 minutes. In 2007, the sts-7 system was approved. Using a disposable sensor, the sts-7 measures glucose levels for up to a week. An alarm will sound if glucose levels are too high or low. The older minimed system measures glucose over a 72-hour period and has wireless communication between the monitor and an insulin pump.
Glucowatch is a battery-powered wristwatch-like device that measures glucose by sending tiny electric currents through the skin, a technique called reverse iontophoresis. It is painless and has a warning device when detecting high glucose levels. It takes 2 hours to warm up, and the sensor pads need to be changed every day. Glucowatch measures glucose levels three times per hour for up to 12 hours. About a quarter of the time, the results differ significantly from actual fingerstick tests, however.
Hemoglobin a1c (also called hba1c, ha1c, or a1c) is measured periodically every 2 - 3 months, or at least twice a year, to determine the average blood-sugar level over the lifespan of the red blood cell. While fingerprick self-testing provides information on blood glucose for that day, the hba1c test shows how well blood sugar has been controlled over the period of several months. For most people with well-controlled diabetes, hba1c levels should be below 7%. Home tests are available for measuring a1c but they tend not to be as accurate as the laboratory tests ordered by doctors.
Urine tests are useful for detecting the presence of ketones. These tests should always be performed during illness or stressful situations, when diabetes is likely to go out of control. The patient should also undergo yearly urine tests for microalbuminuria (small amounts of protein in the urine), a risk factor for future kidney disease.
I am diabatic since feb 2016. Now taking insulin from last two year. I am facing knee pain and joint pain from last 9 - 10 months. Please advice me for better treatment.
Hello Doctor, I'm 25. My father has diabetes and his father had too. What should I do to avoid getting diabetes? Please advice.
My age is 24 years , I have diabetes since one year and now it is high pp 300 . Is it possible to lower my sugar level without taking medicines ?
I am 19 years old male and I am suffering from thyroid from 2 years to get rid from this I am using a medicine named thyronorm. Bt still it is not giving relief to me my face always swells after waking from bed. I can not understand what should I do.

I am suffering hyper thyroid. Since 2009. And now I am taking neo mercazole tablets 5 mg. Per day. Give me permanent remedy.
I want to ask is it necessary to take thyroid medication if my t3 and t4 are normal but tsh is raised from normal range. Kindly tell me.
What is High Blood Pressure?
High blood pressure or hypertension is a condition caused when the force of the blood against the arterial walls exceeds drastically than what it normally is. A blood pressure reading exceeding 140/90 over a prolonged period of time is considered to be ‘high blood pressure’ or diagnosed as ‘hypertension’.
What is Diabetes?
Diabetes is characterized by extremely high levels of blood glucose (blood sugar) in the body, either due to the insufficient secretion of insulin by the pancreas or reduced sensitivity of the body to insulin. This makes your body unable to break down the sugars. At first glance, these two conditions seem completely unrelated, but, according to certain studies, the two conditions do have similar outcomes and could be inter-dependent.
According to the American Diabetes Association, the combination of hypertension and type 2 diabetes is particularly lethal and can significantly raise a person's risk of having a heart attack or stroke. Having type 2 diabetes and high blood pressure also increases your chances of developing other diabetes-related diseases, such as kidney disease, and retinopathy (eye blood vessels), which may cause blindness. There is substantial overlap between diabetes and hypertension, reflecting substantial overlap in their etiology and disease mechanisms. Genetic structure, Obesity, inflammation, oxidative stress, and insulin resistance are thought to be the common pathways. A prospective cohort study in the United States reported that type 2 diabetes mellitus was almost 2.5 times as likely to develop in subjects with hypertension as in subjects with normal blood pressure.
In the Hong Kong Cardiovascular Risk Factor Prevalence Study, only 42% of people with diabetes had normal blood pressure and only 56% of people with hypertension had normal glucose tolerance. There are many minor lifestyle changes that can lower your blood pressure and blood sugar. A brisk walk for 30 to 40 minutes every day, or any aerobic activity can make your heart healthier. In addition to lowering blood pressure and blood sugar, physical activity can strengthen the heart muscle and may reduce arterial stiffness. You may need minor modifications in your diet like, cutting out sugar salt, high-fat meats etc. You can take several servings of vegetables, low-fat dairy products, leans meats and fish or meat substitutes, fruits, whole (not processed) foods, whole-grain pastas, breads, and brown rice etc. While some people can improve their type 2 diabetes and hypertension with lifestyle changes, most require medication.
Depending on their overall health, some people may need more than one medication to reduce their risk. Consult your doctor to choose best possible medicines for your diabetes and / or blood pressure control.
