Best Way To Take Insulin At Home

Many long standing Type 2 diabetes patients and Type 1 diabetes patients need to take daily insulin injections at home for maintaining their blood sugar level under control. Insulin is available in market in two injectable forms:  insulin vials or insulin pen (use & throw flex pen or re-fillable pen with cartridges).

Where to inject insulin (Sites) ?

Insulin is injected subcutaneously, i.e just below the skin in fatty tissue. If insulin is injected deeper in muscles then it may get absorbed quickly and can lead to low sugars. Insulin should not be given in scars, moles, varicose veins, sites with broken blood vessels etc. as it may alter its absorption. Insulin injection site must be rotated each time to avoid lypodystrophy (Atleast take insulin injection an inch apart from previous site).

Sites where you can take insulin injection :

  1. Abdomen : this is the most preferable site for self administration since absorption of insulin is quicker and predictable. You can take insulin atleast two fingers width away from belly button.
  2. Thigh : This is second best site after abdomen for self administration of insulin injection. Top and outer aspect of thigh is preferred. Avoid injecting insulin on inner side of thigh.
  3. Arms : Normally when somebody else is administrating insulin to diabetes patient it can be given on outer back aspect of arm away from shoulder and elbow in fatty tissue.
  4. Buttocks : Upper outer padded part (wallet area) is preferred spot.

How to take or inject insulin ?

Insulin is stored in refrigerator  (In door shelf or tray but not in ice box part). Take insulin vial or pen out of refrigerator and allow it to come to room temperature (10-15 mins). Mix insulin via rolling insulin vial in your palms, do not shake insulin vial. Bolus and premix insulin should be taken before food (Regular insulin like actrapid and huminsulin R or premix like human mixtard 30/70 or huminsulin 30/70 should be taken 20-30 mins before food, Incase of rapid acting analogues like Humalog, Novarapid, Novomix 30, Humalog 25/75 etc can be taken just prior to meal)

Steps to follow for injecting insulin via Insulin vial

  1. Wash your hands thoroughly before taking insulin.
  2. Hold the syringe in upright position (Needle on top) and pull the plunger down until the tip of the plunger reaches the measurement equal to the dose you will inject.
  3. Remove cap of insulin vial & syringe, push the needle into the stopper and push the plunger down. The air replaces the amount of insulin you will withdraw.
  4. Keeping the needle in the vial, turn them upside down. Pull the plunger down until the black tip of the plunger reaches the correct dosage on the syringe.
  5. If there are bubbles in the syringe, tap it gently and the bubbles will rise to the top. Push the syringe to release the bubbles back into the vial. Pull the plunger down again until you reach the correct dose.
  6. Keep insulin vial down and hold a syringe like a pen
  7. Pinch the skin and Insert the needle at a 90-degree angle.If you are injecting into a site with less fat, injecting at a 45-degree angle is fine. Push the plunger all the way down and wait for 10 seconds before removing the needle.

Steps to follow for injecting insulin via Insulin pen :

  1. Wash your hands thoroughly before taking insulin.
  2. Clean the site with cotton where insulin is injected.
  3. Remove the top cover part of insulin pen and attach needle to insulin pen by rotating it on upper side.
  4. Fix the number on dial on bottom side of pen equivalent to dose of insulin you need to inject. (normally 1 click = 1 unit)
  5. Pinch the skin and insert the needle at a 90-degree angle. Press the bottom part button of the pen till the dialer resets to Zero Again.
  6. Hold it for 10 secs till complete amount of insulin gets injected.
  7. Loose the skin and remove needle slowly.

Self Monitoring of Blood Glucose – SMBG Chart Free Download

Self monitoring of blood glucose (SMBG) is very crucial for those diabetics who are on insulin or on certain oral anti-diabetic drugs which can cause hypoglycemia. To achieve best glycemic control it is essential to know how your daily blood glucose levels are fluctuating in entire day.

It is easier for a diabetes specialist to adjust drugs or to adjust insulin dose if good SMBG record is maintained by the patient.

Normally we check fasting and 2 hr post prandial blood sugar levels in lab for routine follow up. There is bright chance of sugar excursions in the other post meal readings which gets unnoticed.  Even in case of HbA1c or Glycated hemoglobin test we get an average result of blood glucose of last 3 months.

In practice I have seen several patients who had fasting and post prandial blood glucose lab tests in normal range but HbA1c levels below 7 is not achieved because they might have high blood sugars in other post meals which has got unnoticed.

To achieve best blood glycemic control it is important to control blood sugar levels within normal limits during entire day and not just fasting or post breakfast levels.

Interpretation of SMBG Chart :

In the above image of SMBG chart I have mentioned 7 point charting system where you can fill your blood glucometer readings which you take on several spots in an entire day.

Seven Points includes :

  1. Fasting or before breakfast reading
  2. 2 hrs after breakfast
  3. before lunch
  4. 2 hrs after lunch
  5. before dinner
  6. 2 hrs after dinner or bedtime
  7. At mid night 3.00 AM

This seven point SMBG charting approximately covers entire day glucose fluctuations to some extent (ofcourse  not as accurate as CGMS).

I have also mentioned a comment column in the above SMBG chart where you can note down change in food or change in insulin dose or any other changes that you have made which probably caused unusual readings like for example if Hypoglycemia occurs at before lunch reading and you have skipped breakfast or had very little snack at breakfast you can mentioned that.

You do not need to check daily all the 7 points, you can check any one or 2 points randomly depending upon your sugar control.

More uncontrolled blood sugars requires more frequent SMBG glucometer monitoring.

Monitoring of blood glucose at home in case of diabetic pregnancy or gestational diabetes is also important where frequent monitoring and SMBG charting of glucometer readings helps a lot to patient.

Download SMBG chart in PDF format below and take print of it.



I hope this article will help you to control your blood sugar levels more efficiently.

If you find that some of the post meal or pre meal readings are high or low, please consult your diabetologist with SMBG chart to adjust your medication or insulin dosage.

Find Out The Most Reliable Test for Diabetes

HbA1c or Glycated Hemoglobin is most reliable test for confirming diabetes. HbA1c measurement has a central role in management of diabetes. HbA1c levels can be directly related to the risk of development of diabetic complications.

What is HbA1c (Glycosylated Hemoglobin) ?

Hemoglobin in blood reacts spontaneously with glucose to form glycated  derivatives in a non enzymatic manner. The process occurs slowly, with the extent of glycation determined by the concentration of glucose in the blood. Human hemoglobin A undergoes such glycation to form HbA1c from a reaction between the Beta chain of  hemoglobin A0 and glucose. Other compounds result from similar reactions on the alpha and beta chains of hemoglobin and these can be measured as the total glycated hemoglobin.

Which conditions affect HbA1c levels ?

Glycated hemoglobin can be affected by the presence of hemoglobin variants and uremia. Vitamin C, Hemolytic and Iron deficiency anaemia can also give abnormal results. Other conditions in which there is a rapid turnover of red blood cells ( e.g. polycythemia, anaemia or blood transfusion) can also give inaccurate results.

Why HbA1c (Glycated Hemoglobin) is most reliable test for Diabetes ?

HbA1c (Glycated Hb) serves as a retrospective indicator of the average glucose concentration over the previous 6-8 weeks. Approximately 50% of the variance in HbA1c is determined by the average blood glucose concentration over the previous month. 25% by the concentration over 30-60 days, and the remaining 25% by the concentration from 60 -120 days ( Red blood cells have lifespan of around 120 days).

  • HbA1c offers a potentially easier, non -fasting and therefore more acceptable test.
  • There is less intra individual variation with HbA1c than glucose testing. ( Fasting blood sugar test can vary in intra individual depending on hours of fasting, quantity and quality of food consumed )


How HbA1c is interpreted ?

Results of HbA1c can be interpreted for diagnosis of diabetes as :-

5.6 % and below = Normal

5.7 – 6.4% = Pre-diabetes

6.5% and Above = Diabetes 

At the time of diagnosis if you have HbA1c of less than 5.7 % that means you do not have diabetes (excluding conditions affecting HbA1c readings mentioned above). If your reading is between 5.7% -6.4 % then you are in Pre-diabetes stage i.e. you have risk of developing diabetes. At this stage diabetes can be reversed to normal with diet, exercise (weight loss) and certain medication which enhances insulin sensitivity. 6.5% And above HbA1c indicates established diabetes. If your blood sugars are in Pre-diabetes range or established diabetes range then consult diabetes specialist immediately.

In already established diabetic person HbA1c monitoring helps diabetologist to check the control of blood sugar in preceding 3 months and can titre medication according to it.

According to ADA guidelines HbA1c of < 7 % is the goal for diabetes management. In younger patients tight control (HbA1c of 6.5%) is even better in minimizing the complications of diabetes.

It has been proven by DCCT & UKPDS trials ( Type 1 & 2 diabetes patient study) that reduction in HbA1c even by 1 % reduces majority of microvascular complications ( retinopathy, neuropathy, nephropathy) & macrovascular complications ( peripheral vascular disease, amputations, heart failures).

HbA1c is also used for monitoring sugar control progress during pregnancy.

That was all about HbA1c (Glycated Hemoglobin) and its use.

6 Ways to Treat Constipation in Diabetes at Home

Majority of diabetic people suffer from constipation, irregular bowel movements, abdominal cramps, dyspepsia, etc. Uncontrolled diabetes or Hyperglycemia affects nerves that supplies gastro-intestinal tract and hampers peristalsis. This leads to stagnancy of food in gastrointestinal tract. Diabetes also affects the nerves which supplies pyloric sphincter, causing disturbances in its relaxation, which ultimately leads to delayed gastric emptying. Nerves supplying to antrum of stomach are also affected leading to improper crushing of food and accommodation of food in stomach. This finally leads to dyspepsia & constipation. Normally, food we eat reaches rectum in around 36 to 48 hrs. In diabetic person due to imbalance in gastric motility this time span gets further delayed.

6 ways to treat constipation in Diabetes at home

You can treat constipation in diabetes with following six ways :

  1. Increase Fibre in diet – There are two types of fibre in diet (insoluble & soluble). High fibre diet helps to form bulk of stool, also increases water content of stool, makes it soften so it can easily pass through gastro-intestinal tract. Cereals, whole grains, beans are reach in fibre content. Green leafy vegetables, Fruits like apples, pearsberries etc are good for diabetic people. Breakfast with oats helps to get good amount of fibre at the start of the day.
  2. Drink lots of water – If you do not drink good amount of water, body ultimately tries to take water from food you eat & making stools harder. If you are increasing fibre in diet then increase water consumption as well. Drink atleast 1.5 litre of water daily.
  3. Regular Exercise – Regular exercise is necessary for all diabetics. It not only helps in controlling blood sugars but also helps to pass food further in gastro-intestinal tract. Even a moderate amount of exercise in the form of brisk walking or cycling helps to prevent constipation.
  4. Natural Probiotics – Daily a cup of yoghurt or a glass of Chass helps to keep healthy intestinal bacterial flora leading to good digestion of food and preventing constipation.
  5. Laxatives – Laxatives can be of different types like bulk forming, Osmotic, Stool softeners, bowel stimulatory. etc. Isbgol Powder and castor oil are commonly used home made laxatives. It is advisable to consult your diabetes doctor before starting any laxatives.
  6. Last but not the least Excellent Blood Sugar control with diet, exercise and regular timely medication plays and important role in treating constipation in diabetes. Cause of constipation can vary from Nerve damage of GI tract due to long term poor management of diabetes to just simple lack of fibre in diet.

Extreme cases of constipation like Fecal impaction more commonly affecting elderly and disabled bed ridden individuals requires enema or manual evacuation of hard stools by inserting one or two gloved fingers in anus.

Those were the Natural ways of treating constipation in diabetes at home.
