THE DOCTORS 101 CHRONIC SYMPTOMS AND CONDITIONS #25: KIDNEY STONES

Kidney stones are more common than you think, and over the span of life, afflict 1 out of 10 people, more commonly men. The pain is sharp, spasmodic and severe; it is described as being worse than the pain of childbirth. The pain is breathtaking, and if you have “renal colic”, your
world is truly “ in a grain of sand”.

This sand, this tiny rock, forms when certain elements and compounds become too concentrated in the urine as it is formed in your kidneys, and “drop out of solution”, or precipitates. This little pebble, which I’m sure feels like a rock, then begins its long, painful journey down the drainage system of the kidneys, and eventually passes, you hope, out with the
urine.

Be sure to save it for analysis if it does. Sometimes it is arrested, causes the urine to “back up”, and you need assistance to get it out. Half of the kidney stone attacks recur, and you will get other attacks.

This is particularly the case if your first attack comes when you are young, or there is a history of kidney stones which runs in your family. It is important for a doctor, such as an internist, to review your case, particularly if you are young.

Your family history, lifestyle including diet, medications, and other problems may give clues which will allow other attacks to be avoided. Sometimes there are serious underlying conditions that should be addressed. Half of people who have kidney stones have a genetic cause, but even here there are lifestyle changes which will help..

Drinking plenty of liquid helps, unless you have kidney failure. Read the Mayo Clinic article referenced below for details. They are interested enough in kidney stones to have consulted a Geologist, the ultimate student of Rocks.

COVID-19 INFOGRAPHIC: ‘EXERCISE IS MEDICINE’ (BMJ)

There are over 35,000,000 reported cases of COVID-19 disease and 1 000 000 deaths across more than 200 countries worldwide.1 With cases continuing to rise and a robust vaccine not yet available for safe and widespread delivery, lifestyle adaptations will be needed for the foreseeable future. As we try to contain the spread of the virus, adults are spending more time at home. Recent evidence2 suggests that physical activity levels have decreased by ~30% and sitting time has increased by ~30%. This is a major concern as physical inactivity and sedentary behaviour are risk factors3 for cardiovascular disease, obesity, cancer, diabetes, hypertension, bone and joint disease, depression and premature death.

To date, more than 130 authors from across the world have provided COVID-19-related commentary on these concerns. Many experts4 have emphasised the importance of increasing healthy living behaviours and others5 have indicated that we are now simultaneously fighting not one but two pandemics (ie, COVID-19, physical inactivity). Physical inactivity alone results in over 3 million deaths per year5 and a global burden of US$50 billion.6 Immediate action is required to facilitate physical activity during the COVID-19 pandemic because it is an effective form of medicine3 to promote good health, prevent disease and bolster immune function. Accordingly, widespread messaging to keep adults physically active is of paramount importance.

Several organisations including the WHO, American Heart Association and American College of Sports Medicine have offered initial suggestions and resources for engaging in physical activity during the COVID-19 pandemic. Expanding on these resources, our infographic aims to present a comprehensive illustration for promoting daily physical activity to the lay audience during the COVID-19 pandemic (figure 1). As illustrated, adults are spending more time at home, moving less and sitting more. Physical activity provides numerous health benefits, some of which may even help directly combat the effects of COVID-19. For substantial health benefits, adults should engage in 150–300 min of moderate-to-vigorous intensity physical activity each week and limit the time spent sitting. The recommended levels of physical activity are safely attainable even at home. Using a combination of both formal and informal activities, 150 min can be reached during the week with frequent sessions of physical activity spread throughout the day. Sedentary behaviour can be further reduced by breaking up prolonged sitting with short active breaks. In summary, this infographic offers as an evidence-based tool for public health officials, clinicians, educators and policymakers to communicate the importance of engaging in physical activity during the COVID-19 pandemic.

BRAIN RESEARCH: 40% OF DEMENTIA CASES PREVENTED WITH LIFESTYLE CHANGES

“We are learning that tactics to avoid dementia begin early and continue throughout life, so it’s never too early or too late to take action,” says commission member and AAIC presenter Lon Schneider, MD, co-director of the USC Alzheimer Disease Research Center‘s clinical core and professor of psychiatry and the behavioral sciences and neurology at the Keck School of Medicine of USC.

LOS ANGELES — Modifying 12 risk factors over a lifetime could delay or prevent 40% of dementia cases, according to an updated report by the Lancet Commission on dementia prevention, intervention and care presented at the Alzheimer’s Association International Conference (AAIC 2020).

Twenty-eight world-leading dementia experts added three new risk factors in the new report — excessive alcohol intake and head injury in mid-life and air pollution in later life. These are in addition to nine factors previously identified by the commission in 2017: less education early in life; mid-life hearing loss, hypertension and obesity; and smoking, depression, social isolation, physical inactivity and diabetes later in life (65 and up).

Schneider and commission members recommend that policymakers and individuals adopt the following interventions:

  • Aim to maintain systolic blood pressure of 130 mm Hg or less from the age of 40.
  • Encourage use of hearing aids for hearing loss and reduce hearing loss by protecting ears from high noise levels.
  • Reduce exposure to air pollution and second-hand tobacco smoke.
  • Prevent head injury (particularly by targeting high-risk occupations).
  • Limit alcohol intake to no more than 21 units per week (one unit of alcohol equals 10 ml or 8 g pure alcohol).
  • Stop smoking and support others to stop smoking.
  • Provide all children with primary and secondary education.
  • Lead an active life into mid-life and possibly later life.
  • Reduce obesity and the linked condition of diabetes.

DIET STUDIES: HIGH-SUGAR DIETS SUPPRESS DOPAMINE, LEADING TO OVEREATING

From Phys.org/Univ. of Michigan (June 9, 2020):

High-Sugar Diet Dampens Release of Dopamine Causing Overeating - Univ of Michigan - Credit Christina May and Monica Dus

“On a high-sugar diet, we find that the fruit flies’ dopaminergic neurons are less active, because the high sugar intake decreases the intensity of the sweetness signal that comes from the mouth,” Dus said. “Animals use this feedback from dopamine to make predictions about how rewarding or filling a food will be. In the high-sugar diet flies, this process is broken—they get less dopamine neuron activation and so end up eating more than they need, which over time makes them gain weight.”

It is well known that consuming food and drink high in sugar is not great for us, but scientists are continuing to unravel the intricacies of how the sweet stuff drives negative health outcomes. The latest finding comes from researchers at the University of Michigan, who through studies in fruit flies have found that excess amounts of sugar can shut down crucial neural circuits linked to regulating satiety, possibly leading to overeating in humans.

COMMENTARY

SUGAR IS A POISON.

A novel illustration of sugars’ lethality was the Georgia sugar refinery explosion in 2008, which killed 14 people. Finely ground sugar is flammable.

Sugar appeared early in civilization, but it was expensive, sparing all but the wealthy of its’ depredations, mainly tooth decay.  Only with the post WWII expansion of wealth was it consumed excessively to produce the diseases of overeating. The developed world now consumes over 70 pounds of sugar per person, amounting to over 250 CALORIES PER DAY!

This  article shows how SUGAR acts like a DRUG In its INTERFERENCE with the DOPAMINERGIC Reward system. The neurons send less signal, so you need MORE SUGAR to satisfy.

The metabolic systems through which overeating and sugar causes the OBESITY, DIABETES, VASCULAR DISEASE and Early DEMENTIA are convoluted.The best detailed explication is in the NEJM article in intermittent fasting, a healthful practice that is the polar opposite of overeating.

Two very important metabolic mechanisms are discussed, the mTOR system and the Sirtuin system. These systems are important for NUTRIENT SENSING and repair, and conserved in all animals. They worked just fine in our early ancestors.

It seems that primitive man was not blessed (or is it cursed) with easy overabundance or food, and actually spent hours or days in Hunger. When times were good, his body put on muscle, and stored fat against the hard times to come. This is called ANABOLISM. When times were bad, his body went into repair mode, and used the fat for energy. This is called CATABOLISM.

Anabolism has evolved expressly for Young Animals, where extra food is welcome for Growth. After the growing and Reproductive years, our Bodies’ evolutionary “warrant” expires, since the genes it carries have already been spread. Our older bodies are left to deal with machinery more suited to an earlier vibrancy. Our metabolism didn’t evolve to deal with the calories we shove into our aging Bodies. Many mechanisms beneficial in the young prove harmful later on. This divergence has been called “ antagonistic pleiotropy”.

Whatever the explanation, the observation remains: if adults eat more than they can use, they gain weight. With insufficient exercise, this weight is fat. With excessive fat, the joints, blood vessels, liver, heart and brain suffer,  and lifespan is shortened.

RETHINK YOUR LIFESTYLE AS SOON AS POSSIBLE. AVOIDING SUGAR, and ALL THINGS CONTAINING SUGAR is as good a place as any to start. You will be rewarded by being able to fully taste and enjoy the natural sweetness of many REAL FOODS, and afforded a longer life to partake in this pleasure.
