When you’re insulin resistant, that is, you’ve got  metabolic syndrome, pretty much every chemical in the body is NOT QUITE RIGHT.  Some are up.  Some are down.  Few are actually at physiologically NORMAL levels.

Traditionally the focus is on the big guns.

  • Sugar
  • Insulin
  • And cholesterol

In this series, we  take a look at some of the other players.

Who they are, what they’re up to and how they’re part of the state of insulin resistance.

Salivary gland function in insulin resistance

When you’re insulin resistant –  you typically, produce less saliva and the composition of the saliva, is altered.

It manifests as a dry mouth.

When it is bad enough, to notice, it is referred to as xerostomia. Most people notice it, when there is a 40 – 50 % loss of function of the salivary glands. But long before, this happens, you will be experiencing the consequences of salivary hypofunction, because saliva, is a magical elixir, which protects, lubricates and hydrates oral surfaces of the mouth.

You need it

  • To swallow
  • To talk
  • To taste
  • To chew

It influences who lives in your mouth. And, this determines, how healthy your gums and teeth are. And this in turn,  impacts heart, brain and lung health.

the oral systemic connection

So what is saliva ?

A spit-acular fluid

Well, it’s a very complex fluid,  containing over 2000 different proteins, made by salivary glands.

A few are unique to saliva, most are not.

In fact, salivary glands are able to produce insulin !

Glands………..with an S

There are the BIG ones,  these are  referred to as the major salivary glands, these include the parotid, sublingal and submandibular.

And then there are the minor ones.

There are somewhere between 800 and 1000 of them,  dotted throughout the oral cavity

In a single day,  you will make and swallow, somewhere between 0.6 – 1.5 L of saliva.   But at any given point in time, there is around  0.7 – 1 ml of saliva in mouth.

The life and times of a salivary gland

Eating, turns on the tap, but when you’re resting, saliva is still produced.

timing of saliva productionSaliva levels follow a circadian rhythm : levels are at their lowest, first thing in the morning (6 am) and reach their peak,  12 hours later, around 6 pm.

There actual  production, is regulated by the autonomic nervous system, both, sides make a contribution…………

The parasympathetic nerves control the amount.

The sympathetic nerves, control the composition.

Why is there a trickle and not a torrent, when you’re insulin resistant ?  No one knows for sure.

The empty spit-tootle

salivary gland pumping poorly

Saliva gland atrophy has been suggested.

This is thought to be sparked, by decreased nerve stimulation and/or poor microcirculation.  In the case of insulin resistance, this is arising  because of the  hyperinsulinemia and it differs from the atrophy, that happens in Sjorgren’s syndrome.  The atrophy in Sjorgren’s  syndrome, an autoimmune disease, is brought on when  the immune system, continuously takes pot shots, at the salivary glands.

The insulin effect..

The worse the  body chemistry, the bigger the problem.

Initially the troubles are due to microcirculation problems, problem brought on by shortages of nitric oxide.  These microcirculation problems, manifest relatively early…………..studies suggest, overweight kids, already have signs of salivary gland hypofunction.

Poor glycemic control, then takes things up a notch………..

As the excess sugar is cleared by the kidney, it takes body water with it, precipitating dehydration, not just neglect.

Dry mouth a health crisis

A dry mouth is not just a nuisance, it has  serious health ramifications.   It impacts teeth and gums, its hurts the mouth and leads to difficulties chewing, talking and swallowing.

consequences of dry mouth

So it is something that should be on your radar.

Addressing the bad body chemistry, is going to be the place to start, but it is a little unfair, to blame all  salivary problems on insulin, there are a host of other things, that can put strain on salivary gland function.

Salivary gland abuse

Comes in many guises, fortunately many of the factors, negatively impacting salivary function can be managed / addressed.

  • Smoking
  • Alcohol, particularly alcohol based mouthwashes
  • Caffeine consumption – it’s not just in coffee, it’s in many soft drinks
  • Snoring
  • Mouth breathing
  • Upper respiratory infections
  • Fear & anxiety
  • Meds

In terms of medications,  over a 1000  drugs, have been shown to induce dry mouth, the categories of drugs which are known to be problematic, include :  drug capsule blocking the salivary gland

  • anti-depressants
  • anti-psychotics
  • anti-cholinergics
  • anti-hypertensives
  • anti-histamines
  • sedatives
  • anti-diuretics

 

NOTE :  Anti-cholinergics, are a category of drugs, which have many indications, they’re used to treat asthma, COPD, overactive bladder, Parkinson’s disease, as well as Alzheimer’s disease.

If you’re taking a drug, which is having a negative impact on your salivary function,  discuss whether it would be possible to substitute or discontinue the medication with your doctor.  Don’t ever just STOP a medical treatment you’re on, it can have SERIOUS ramifications.

The reality……….. a lot of the time, you cannot PREVENT negatively impacting your salivary glands,  so are there ways to help them out ?

A little spit fire

The strongest stimulant for saliva production,  is chewing / mouth movement.

Unfortunately, eating/drinking all the time,  has it’s own set of issues…. fortunately, there are other options, each with their own  pros and cons.

A technique with lots of pros and only a one con, is tongue hoola.

The tongue hoola hoop

To do it,  you rotate your tongue round the edge of your mouth slowly, a couple of times – alternating between circling clockwise then anti-clockwise.  The technique  costs NOTHING,  and it works like gang  busters, saliva levels increase by 25 % and they stay elevated for a little while.

the benefits of tongue hoola hoop

The con of doing the tongue hoola hoop – you look a little STUPID !

So you might not want to do this one  in PUBLIC.

But, to get the benefits, you MUST DO IT.

And you must do it,  on a regular basis, throughout your day.

women doing the tongue hoola hoopRemembering to do it 

If you’re joined at the hip, to an electronic device, you might want to pair, your tongue hoola hooping, to the “loading wheel”.  Every time the wheel spins, because your device is THINKING, give your tongue a whirl.

If your “computer” is anything like mine, this will ensure, your mouth is bathed in saliva, all day.

There are other things you can do, to mitigate the effects of salivary gland hypofunction.

Beyond tongue hoola hooping

  • The obvious ones, staying adequately hydrated.
  • If the atmosphere, where you live is particularly dry, using a humidifier, will moisten the air and can help stave off dehydration.
  • A more medical approach, would be to use a sialogogue,  this  is a fancy name for a  saliva substitute.  These can be bought ready made, or  you can make a homemade version.
  • A more exotic option is electro-stimulating.  Salivary pacemakers, haven’t gone main stream just yet, but they are coming.

The take home message – when you’re insulin resistant, you need to take care to keep the mouth juice FLOWING.
