DIABETES - WHAT YOU NEED TO KNOW! (PART FIVE)

Human mind is filled with desires. It may be related to profession, personal life or purely to enjoy a cosy life!

Desires are good!

Professional desires help us set targets for ourselves and angle us towards achieving great heights.

Personal desires and wish buckets help us challenge ourselves to a better living!

Without desires life will be Monotonous & Boring.

From time immemorial it has been a neat business trick to capitulate on human desires for better profits!

Give the man what he wants......  He will forgo his fortune to fulfil his desires....


Why am I talking about this?

Well, as we all know Diabetes is spreading far and wide.
India has become the Capital of Diabetes. Chennai is slowly moving towards having 40% of its people affected by Diabetes. 


Now why actually are people scared of Diabetes?


  • Can’t eat sweets!
  • Have to go for walking!
  • Intermittent and excessive snacking has to be controlled!
  • Diet restrictions & Modifications!
Do you think people are scared of these things?
The answer is a pure NO!!
Now in the era of internet dominating our lives diet restrictions and exercise are slowly becoming more common even in a non-diabetic population. People follow these may be for pure weight loss or to prevent Diabetes or just to stay Healthy!

If these are not bothering people why is everybody scared of Diabetes?

It is the puzzles associated with diabetes which scares people....
By puzzles I mean the inner conflict which a person with Diabetes goes through... Every single symptom starts a war of thoughts inside the 1.5kg battle ground called the brain...
Numbness or tingling in feet........ Are my nerves affected? Will I lose my limb? Will I be bedridden?
Lesser urine or passing yellowish urine....... what about my kidneys? Sugar is eating up the kidneys? Dialysis? Kidney transplant?
Slight discomfort in chest ...... Diabetics can have silent heart attacks. Am I having one right now?
These may sound funny or over exaggeration for some of you.  No.... these thoughts do linger in every person with Diabetes!

As Doctors we always suggest some preventive measures. Some specific and some general...

  • Reduce fried foods
  • Reduce salt
  • Avoid sugar and carbonated drinks.
  • Stop smoking
  • Reduce alcohol consumption
  • Check your feet everyday
  • Have regular checkups so that problems may be identified and corrected in the very early stages.
Here comes the business! The profit!

Advances in technology have helped find alternatives for every Doctor’s advice.
Some have worked and some are yet to reach the masses.

Now two things which stand out among the recommendations are

  • Reduce alcohol consumption
  • Stop smoking
Believe me or not! Some company has started advertisements of non-alcoholic whiskey!

Smoking! This is something which the patient lies every time to the Doctor!
“I stopped years ago!!”
“I used to smoke 2 PACKETS  a day... Now I smoke only 2”

It is the pure addiction which makes the person lie for years....The Desire!

Few years back came the E-cigarettes! Claimed to be less harmful than the routine cigarettes. Every mode of personal advertising was exploited..Promises of being a safe alternate to smoking. Innumerable phone calls from companies claiming to sell E-cigarettes, ads in websites and what not....
E-cigarettes were poised to overtake traditional cigarettes in a decade or so...

So how do these basically work?
They look like the real thing. The end glows as you inhale. As you exhale, you puff out a cloud of what looks like smoke. It's vapour! All e-cigarettes work basically the same way. Inside, there's a battery, a heating element, and a cartridge that holds nicotine and other liquids and flavours. Features and costs vary. Some are disposable. Others have a rechargeable battery and refillable cartridges. Using an e-cigarette is called "vaping."
Are these safe?
NO! Nicotine inside the E-cigarette is addictive. You can get withdrawal symptoms including feeling irritable, depressed, restless and anxious.
What we advised all these years?
Not a smoker - Don't start vaping. There are no health benefits and some risks.
Decided to Quit smoking - Better off with an FDA-approved method of quitting, like the nicotine patch or gum.
Not decided about quitting - would it be healthier to switch from tobacco products to e-cigarettes? Maybe! Talk to your doctor about the risks and benefits.

What happened now?
Recent research shows otherwise!
E-cigarettes contain up to 10 times the amount of cancer-causing agents as regular tobacco. Researchers found carcinogens such as formaldehyde and acetaldehyde in vapour produced by several types of e-cigarette liquid. Formaldehyde- a substance found in building materials and embalming fluids- was present at levels 10 times those found in the smoke from regular cigarettes.
Final Conclusion is......
Nicotine in any form is unsafe...
Best way to quit smoking is never in turning to alternatives....
Never fully believe advertisements..... Particularly Health related....
“Everybody lies” to make money....
Your health lies in your hands! Make an informed decision!

DIABETES - WHAT YOU NEED TO KNOW !! (PART - FOUR)

Hi there...

Hope you all enjoyed a beautiful Diwali...

Here in Chennai it was a wonderful weather with Monsoon setting in making Chennai a “cool” place.

Last three weeks I have written about three important topics




Now we will discuss about one of the main PILLARS of diabetes management – Sulphonylureas
.
These classes of drugs were introduced in the 1950’s....  A classical example for “Accidental Discovery”... Yes, the blood sugar reducing potential of these compounds was discovered as a side effect... Actually at that point of time scientists were busy discovering oral antibiotics. When some of the sulphonamides were used for treating infections in diabetic patients they also noticed a remarkable reduction in blood and urine sugar values. This slowly translated into the first generation sulphonylureas – Carbutamide, Tolbutamide, Chlorpropamide and Tolazamide. These drugs were very effective in treatment of Type 2 Diabetes.  These drugs helped millions wean off insulin and live a near normal life. Unfortunately these drugs were taken off due to harmful side effects on bone marrow and blood profile. The next generation drugs which we are using are
Glibenclamide – DAONIL *
Glipizide – GLYNASE *
Gliclazide – DIAMICRON, RECLIDE, GLYCINORM *
The latest member of the family is Glimipride- 3rd Generation Sulphonylurea (AMARYL, GP, GLIMESTAR*). This molecule claims to have a cardioprotective effect and is supposed to give a smoother control of blood sugars.

How do these drugs work?

To put it in very very simple words these drugs bind to receptor on the cell membrane of pancreatic beta cells (insulin producing cells) this binding results in a series of chemical reactions and finally increases the intracellular calcium level in the Beta cell leading to release of insulin. So basically speaking these drugs do not increase insulin production. They only help to bring out the already produced insulin.

How to take these drugs?

For some unknown reasons the timing of these drugs are not given due importance. The mode of action which I have explained here is an over simplified version. It contains more intricate steps which needs time. In order to obtain the full benefit of the drug and to get a proper sugar control Sulphonylureas have to be taken 30minutes before food. This family currently comprises of 4 members and all of them come as plain tablets or in combination with metformin or as a megamix of sulphonylurea + metformin + pioglitazone. Personally i do not prefer using triple drug combinations as dose adjustments becomes more confusing plus the chances of appearance of unwanted side effects are more when such multiple combinations are used.

Disadvantages.

These drugs are like a boon to Diabetic patient saving him from daily pricks for approximately 10-15years. Lucky are those who continue to get better control after 20years with oral drugs. All these drugs come with minimal side effects which may be clinically evident in a very small percentage of patients. So I am not going to discuss about them in detail. But, the most common disadvantage with this group of drugs is that they can push you into severe hypoglycaemia if used inadvertently...

Winding  up....

Sulphonylureas are real pillars for effective management of Diabetes. Used as per recommendations they serve you well. When dosing sulphonylureas the chances of hypoglycaemia have to be kept in mind. Never try to double the dose of half the dose without expert help. I think i have covered the most important drugs used in Diabetes. My next post would be on Newer drugs used in Diabetes..

Till then.....

Take care...

Bye....

DIABETES - WHAT YOU NEED TO KNOW !! (PART III)

Hope you all have enjoyed reading my previous posts on “DIABETES - WHAT YOU NEED TO KNOW”..

Today I am going to explain another drug in a simplest way possible..*

In the last post I had mentioned about Metformin. Today we will be dealing with another class of drugs called ALPHA GLUCOSIDASE INHIBITORS.

Too technical??

Names like GLUCOBAY**, ACARB**, MIGNAR**, ELITOX**, VOBOSE**, VOLIX**, PPG** may sound more familiar.... Right?

These drugs belong to the class of drugs which help in controlling the post prandial blood sugar values. Three major groups are currently available in the market.  In the late 90’s the group ACARBOSE (Glucobay**, Acarb**) was introduced in India. By 2006 VOGLIBOSE (Vobose**, Volix**, Ppg**) was introduced into the market. The main purpose of these groups of drugs was aimed at controlling the post prandial spikes in Diabetics. 

How does this drug work?#

To have a better understanding of this we need to know how the normal body works. Generally speaking the fasting blood sugar level is based on what you eat and also on the amount of glucose being pumped out from the liver. The post prandial values are largely based on what you eat. In normal people the pancreas release insulin in spurts in response to the food you take. So the pizza, burger, chocolates, ice creams or sweets are processed well and blood sugars are maintained in the normal range. As a patient develops Diabetes this normalcy is altered. The first pathology noticed is the altered timing of release of insulin from the pancreas. There is a delay in release of insulin so what happens is that the insulin is released a little later than expected. As there is nobody to regulate the incoming sugars the blood sugar levels slowly start to creep in the post prandial state. During management of Diabetes we face this challenge with majority of patients in India. There is an unexplained peak of blood sugars in the post prandial stage. Here is where this group of drugs help us.



Basically what we eat comes in the form of complex carbohydrates. For effective absorption these complex carbohydrates have to be converted to simple carbohydrates. This function is carried out by an enzyme in the body called Alpha Glucosidase. This alpha glucosidase enzyme is inhibited by these groups of drugs. The result is that the complex carbohydrates cannot be converted to simple carbohydrates and hence cannot be taken up by our system.

How to take alpha glucosidase inhibitors?

The duration of action of these tablets is very short compared any other tablets used in Diabetes management.
The general recommendation is to take the tablet just before food or take one morsel of food, take the tablet and continue with the food..
These tablets are available in plain and as combination with metformin.

Strengths & Potency..

Although the mechanism of action seems very convincing it normally doesn’t prevent the complete absorption of carbohydrates from the food we take. These drugs are generally used as “second line” drugs in management of diabetes. Acarbose & miglitol are available in 25mg and 50mg packing. Voglibose comes in 0.2 and 0.3mg forms.

Drawbacks ..

The incidences of gastrointestinal disturbances are more with this drug. Nearly 20-30% of patients develop Gastritis, Flatulence, and Nausea. In very few cases the side effects are troublesome leading to withdrawal of drug. The side effects can be minimized or prevented by adding appropriate drugs while starting on alpha glucosidase inhibitors (Doctor who examines you personally is the best judge on what drug will prevent side effects in you)
Some patients can have altered Liver Function Test with this drug so it is necessary to check your LFT once in 6months or atleast once a year.

Before I say Good bye....

The class of Alpha Glucosidase inhibitors are a very good option in controlling post prandial blood sugars. They have no effect on the Fasting blood sugars. It is safe to start on a lower dose. Hypoglycemia with is tablet is very rarely. The side effects in the form of gastrointestinal or Hepatitis are to be taken seriously. Doctor is the best judge to decide the dosage and timing of these tablets.

Wishing all my readers a very happy and safe Diwali!!

See you all soon...
