These last few weeks have been interesting and unsettling to say the least…

I’ve watched – right along with you – to see how our government and society responds to the COVID-19 crisis. Some very interesting trends are starting to appear…

But first…

Is Advice to Limit Red Meat Consumption Wrong?

By David Blyweiss, M.D., Advanced Natural Wellness

April 20, 2020

I’ll never tell my patients to completely give up red meat. But I do caution them…

Once a week you can have some clean free range, organic red meat. More than that and you’re asking for trouble.

Now, recent news headlines are starting to preach a different story. And I don’t like what I’m seeing.

An article recently displayed this controversial headline: “No need to reduce red or processed meat consumption.” The concept has become a media darling. Continue reading

Wash Your Brain Clean with a Good Night’s Sleep

By David Blyweiss, M.D., Advanced Natural Wellness

April 15, 2020

For me, getting a good night’s sleep is a serious matter.

That’s why I avoid staying over at other people’s houses whenever possible. I just don’t sleep well… usually because they keep the temperature warmer than I’d like and far above what’s been shown to be an optimal range.

I take this seriously because sleep isn’t just a matter of feeling alert the next day. Good sleep sessions can actually make a long term difference in whether you develop a degenerative brain disease. Continue reading

5 Ways to Stop Dementia Before it Starts

By David Blyweiss, M.D., Advanced Natural Wellness

April 13, 2020

Recently the mother of one of my patients passed away. Debbie was understandably upset. She was also confused…

You see, her mom had been in a nursing home with Alzheimer’s disease. Over the years, she had suffered from many other health problems including heart disease, diabetes and even a few bouts with aspiration pneumonia.

So, Debbie was shocked when she received the death certificate and discovered her mother’s cause of death was listed as A) Severe Dementia and B) Failure to Thrive. Continue reading

3 Overlooked Causes of Chronic Pain

By David Blyweiss, M.D., Advanced Natural Wellness

April 10, 2020

Recently, a patient named J.D. came to me searching for pain relief. He’d been from doctor to doctor searching for a solution, with no clear answers in sight.

He’s not the first patient I’ve seen like this. Many folks who land in my office have gone for years and years without ever receiving an accurate pain diagnosis.

In J.D.’s case, all sorts of health conditions had already been ruled out. He didn’t have multiple sclerosis, bone cancer, diabetic neuropathy, peripheral artery disease or even ALS (amyotrophic lateral sclerosis).

But once the big scary diseases had been ruled out, J.D. felt his physicians simply dismissed him. They acted like he was wasting their time with his continued pain complaints.

They just wanted him out of their office. So, when J.D. came to see me, we took a different approach than many of his other doctors.

We sat down together and talked about what his pain felt like. Where did it occur? How often did it reach a scale of 10?

He described it as a stabbing and burning pain – often accompanied by agonizing spasms and twitches in his feet, legs and fingers.

Next we addressed his lifestyle – the foods he does and doesn’t eat, physical activity, sleep habits and so on. I also inspected his physical appearance – his hair, skin, mouth and fingernails.

Then, instead of sending the poor fellow off for more neurological exams and imaging studies, I drew blood samples. We sent them out for testing. In particular, I was looking for nutritional deficiencies linked to his symptoms and appearance.

It’s this type of detailed examination that sets a functional medicine doctor like myself apart from conventional doctor. We look for the upstream cause of your downstream problem.

In many cases, this comes down to the foods you eat. The most important tool in our toolkit to change someone’s health – mental as well as physical – is what’s on the end of their fork and not at the bottom of a prescription bottle.

Can Addressing Nutritional Deficiencies Cure Your Pain?

So why don’t conventional docs pay more attention to nutrition and lifestyle?

In fact, most mainstream physicians receive very little training on nutrition. At last count, only 26 out of 105 U.S. medical schools required students to take a dedicated nutrition course. This amounts to only 19.5 hour of nutritional training throughout their entire medical school careers!

It’s one reason I trained in functional medicine – to learn how food and nutrition affect all systems of the body. And it sure comes in handy when it comes to diagnosing hard-to-explain pain cases like J.D.’s.

As it turns out, J.D. was suffering from a vitamin B12 deficiency – which is much more common than you might think.

In many cases, low B12 levels aren’t due to the foods we eat. Instead, people’s bodies aren’t properly absorbing the B12 in their system.

If your body can’t absorb vitamin B12 you may experience severe, shooting nerve pain from irritated or damaged nerves. This can happen anywhere on your body. But in J.D.’s case, it displayed as peripheral neuropathy.

Restoring enough vitamin B12 levels helps rebuild nerves, inhibits pain-signaling pathways and protects the myelin sheath that cushions your nerves. It also helps ease symptoms of low back pain.

We started him off on vitamin B12 injections, then transitioned to a sublingual B12 spray. (Using the sublingual version bypasses malabsorption issues.)

Recommendation: If you have unexplained and undiagnosed shooting pain accompanied with spasms, numbness and/or a burning sensation, have your vitamin B12 levels check. A serum or methylmalonic acid test can quickly reveal a vitamin B12 deficiency.

I also tested J.D. for vitamin D. And I wasn’t surprised to learn he was deficient in this nutrient, too.

Most people aren’t aware of this, but vitamin D deficiency causes weakness and cramps in the muscles. It also contributes to aches and pains. It can even make your bones hurt.

And here’s a real eye opener: patients who suffer from chronic pain or have fibromyalgia commonly have low vitamin D levels.

Unfortunately, somewhere between two and four out of every five Americans are deficient in vitamin D. (It just depends on where you place the cut-off, and that’s a controversy all of its own.)

It’s easy enough to boost your levels by supplementing with a vitamin D formula that contains the cholecalciferol form (the most active form) of D3.

Recommendation: Ask your doctor for a 25-hydroxy vitamin D test. Set your goal for maintaining levels of around 65 ng/ml. If you have been diagnosed with an autoimmune disease closer to 75 ng/ml is better.

Even though J.D. wasn’t deficient in magnesium, it’s not uncommon to experience unexplained muscle pain, cramps and neuropathic pain if you are low on this mineral.

And as with vitamin D, people with fibromyalgia often have low levels of this magnesium in their bodies.

When fibromyalgia patients supplement with as little as 600 mg of magnesium malate daily, their fibromyalgia scores show improvement. This includes levels of pain, function, stiffness and fatigue.

In general I recommend 5 mg of magnesium per pound of body weight. Take it in divided doses throughout the day. I like the magnesiums that end in “ate”… glycinate, orotate, malate, gluconate, threonate etc. The malate specifically for fibromyalgia. Just remember that citrate can cause loose bowels – even at a low dose.

I also encourage you to soak in a warm Epsom Salt bath. It’s a perfect remedy for your aches and pains. Not only do these salts help relieve soreness, they also flood your body with magnesium sulfate that gets absorbed into your body through your skin. Just add two cups to your bathwater.

Recommendation: A magnesium RBC blood test is the most precise magnesium blood test you can get. It measures the actual magnesium levels in your cells.

If pain is your enemy, don’t forget to cut inflammatory foods like refined carbs, sugars, artificial sweeteners, omega-6 fatty acids, gluten, processed meats and MSG from your diet. Replace them with healthy, plant-based foods and clean animal proteins that stave off inflammation.

And don’t forget to exercise with regularity!

4 Foods that Steal Your Vision

You know, of all the health problems to have, vision loss is one of the scariest to me. In fact, I’d rather be deaf than lose my ability to read my favorite books.

So when one middle-aged gentlemen came into my office the other day, I needed to be a little blunt about the risks he was taking with his vision.

Now, every physician gets his or her share of patients who would rather not be there for an appointment. This guy was a classic case. Continue reading

I have a medical history taking habit I can use with some new patients…

Let’s say they’re about 20-years-old… they’re having trouble with certain foods and dealing with off and on intestinal pain, frequently with diarrhea, occasionally with a bit of blood in the toilet bowl.

In no time at all, I can start making a few assumptions about their early childhood… Continue reading

Travel Precautions to Keep Safe from Coronavirus

March 25, 2020

The situation is changing rapidly as the world reacts to the coronavirus pandemic.

I don’t use the word ‘pandemic’ to frighten you. Instead, it’s simply a term that means the disease has spread through multiple countries. So by definition, it’s a worldwide pandemic. It’s gone from Asia, to Europe, to North America.

You’ve likely noticed that widespread traveling is becoming less and less likely. Still, there may be situations where you are forced to travel in close quarters with others in the coming weeks. Continue reading

Things are going to be a bit strange for the next few weeks. The coronavirus pandemic has been a non-stop presence in the news and in people’s minds.

In fact, I was thinking about it myself on the way to Publix the other night. I was headed there to pick up some water and frozen foods. So I could be prepared for the days ahead.

Yes… preparation is the key here. We should all prepare ourselves so we are more likely to stay healthy as this illness spreads through our population. Continue reading
