Your blood pressure is influenzed by hot to cold weather


Heart expert Dr. Padmanabhan has discovered that there is a connection between a drop in temperature during the day to your blood pressure (BP).  This may be because the arteries and veins tend to collapse with colder weather making it harder for blood to travel around the body.  This response to temperature changes may be under genetic control too. Which means some families may be more susceptible to temperature changes than others, so all people may not respond in the same way to weather changes. Those susceptible are 30% more likely to die from a deadly rise in BP than those who are not.

These heart experts realize that not many studies have correlated effect of weather on BP and recommend that physicians be aware of this. Quote

Temperature-sensitive subjects had significantly higher mortality (1.35 [95% confidence interval, 1.06–1.71]; P=0.01) and higher follow-up systolic blood pressure (1.85 [95% confidence interval, 0.24–3.46]; P=0.02) compared with temperature-nonsensitive subjects. Blood pressure response to temperature may be one of the underlying mechanisms that determine long-term blood pressure variability. Knowing a patient’s blood pressure response to weather can help reduce unnecessary antihypertensive treatment modification, which may in turn increase blood pressure variability and, thus, risk.

Unquote.
Sunshine plays a role in monitoring BP. Cloudy days raise BP.

Race, ethnicity and kidney disease


African Americans, Hispanics, and American Indians are at high risk for developing kidney failure. This risk is due in part to high rates of diabetes and high blood pressure in these communities. Is this risk genetically pre-determined and further assisted with inferior diet choices? Will it be inethical for your doctor to advice you based on your ethnicity, if you face a higher chance of getting kidney failure in the future, based on genetically supported scientific data?  Below (under related articles) is more information about kidney failure for each of these groups, prevention and maintenance steps.
Kidney Disease

Rising diabetes and high blood pressure are the leading causes of kidney failure. Since the year 2000, the number of Hispanics with kidney failure has increased by more than 70 percent. While African Americans account for only 13 percent of the population, they account for more than 32 percent of the population with kidney failure.

Diabetes
If you have diabetes or high blood pressure, and are African American, you must strongly consider getting checked for kidney disease. Read more. Diabetes is the number one cause for kidney failure among African Americans, and high blood pressure is a close second. The goal is to keep blood pressure below 130/80, suggests the National Institute of Health.

High sugar diets can lead to diabetes. The fact is that ready-made food is made more appealing by adding sweeteners. Also, several cheap alternatives to sugar may be more dangerous than sugar itself. The poorer the person, the likelier that person is to choose a cheaper food, which might be sweetened to make up for the lack of taste from fresh food. Eating such sweetened food too often can lead to higher risk of diabetes. It is not surprising that the poorer people are getting more obese – another side reaction to eating sweetened food and drinking sweetened beverages. Diabetic persons are frequently obese from such food and beverage choices.  You might want to read “For the First Time in Human History, Overweight People Outnumber the Underfed“, by blogger Mother Nature’s Diet. Scientists have known for several decades that this obesity epidemic is restricted to specific, inferior diet choices, and dictated by differences in the genes inherited from family. Certain ethnic groups will get more obese simply because they do not inherit the genes required to “digest” or “metabolize” inferior food choices. Will it be inethical of the doctor to tell them that the eight year old, 300 pound little child is obese because of her ethnicity, dictated by the genes she inherited from her family, not giving her the ability to digest her fatty and sweetened school lunch? Which country has the highest obesity? Which country has the highest percentage of obese people? You might enjoy reading that the answer to the first is Mexico and the second is Nauru, a small country in the South Pacific (their inherited genes) in “Is this a Good Thing“, which summarizes the United Nation’s Food and Agriculture report.

A refreshing, non-scientific travel observation by blogger gaelic girl on “Victoria’s view: Why are Americans so obese compared to the Irish“, discusses smaller food portions, organic groceries, walking instead of using automobiles for errands, and higher rate of smoking among the Irish. It does not discuss their inherited genetics, since it isn’t scientific, but nonetheless, brings up excellent discussion topics on how to prevent obesity perhaps with the above life style choices, based on the observation that Irish people are a lot skinnier than the Americans, and are not even on the top 25 in the list of obese countries by United Nation’s Food and Agriculture report.

Genetically, there are certain ethnic groups far more at risk for diabetes and high-blood pressure and hence, kidney disease. The genes and junk regions around the genes that you inherited from your parents do define you (Read more). You might wonder why your friend can eat the same foods as you and yet not gain any weight or be at risk for diabetes, while you could be getting obese and at risk for getting diabetes followed by kidney disease.

High Blood Pressure
High blood pressure is another indicator/ risk factor of kidney disease with significant ethnic differences.

….compared to Caucasians, Afro‐Caribbeans and people of African descent have a higher incidence of stroke and end‐stage renal failure, whereas coronary artery disease is less common. Conversely, South‐Asians (defined as people originating from the Indian subcontinent and East Africa) have a higher incidence of coronary heart disease….

Read more. Quoted above from a study of patients in the United Kingdom, such ratios are similar in other developed countries with rising rates of high blood pressure.

In a landmark study, 18 genes have been discovered to be co-related with most of the deaths from heart disease, Britain’s biggest killer. Read more. A few ethnic groups account for most of the deaths from this killer disease, because they inherit these culprit genes from their families.

Getting to know your family takes on a whole new meaning with the knowledge that your biological inheritance from your family also determines your health and longevity. However, this same knowledge allows you to take prevention steps from this moment. You may have to have more self-control than a friend who lacks the culprit genes, but it may save your life.
