Stress hormone measured in hair linked to persistent obesity, study finds
By abcnews.go.com
People with long term stress may be more likely to be obese, according to a recent study by scientists at the University College London, and the telltale signs can be found in strands of hair.
The paper published today in the journal Obesity found that people who have a higher level of the stress hormone cortisol, which affect's the body's metabolism and how it distributes fat, over a long period of time may be more likely to be obese. Their levels of cortisol were measured through hair samples.
This study is part of growing body of evidence linking stress and excess weight gain, including obesity, which is linked to higher risk for heart disease and cancers, according to the World Health Organization.
"We don’t know what is the true relationship between stress and obesity," Sarah Jackson, a research associate at the Institute of Epidemiology & Health at the University College of London. "We know there’s a relationship there but we don’t know if it’s stress causing obesity or obesity causing stress."
To better understand the long-term relationship between weight and stress over time, researchers looked at information from multiple 4-year periods starting in 2002. They compiled data on cortisol and body measurements from 2,527 men and women between the ages of 54 and 87 who were participating in the English Longitudinal Study on Ageing.
Cortisol levels were examined in study participants' hair at 2 time points, 4 years apart to determine the relationship between persistent obesity and hair cortisol levels.
Researchers cut a lock of hair from each participant as close to the scalp as possible. Hair grows approximately 1 cm a month and 2 cm of hair was obtained to represent two months of time. Measurements of hair cortisol levels, as well as body height, weight, and waist circumference were taken to determine obesity trends over time.
Scientists found those who had higher hair cortisol levels had a tendency to be larger and weigh more. In general, they also had the largest waists, were the heaviest in weight and had the highest body mass indexes (BMI).
Those considered to be obese or having a waist greater than 44 inches in men or 34.5 inches in women had the highest levels of stress hormone compared to other subjects.
The study authors acknowledge that the findings are preliminary and a vast majority of the subjects studied so far, 98 percent, where white and British. The data were also from people older than 50 and from only the most recent assessments since tests for hair cortisol have been established.
While preliminary, Jackson said the findings may help encourage people to take steps to diminish stress in their life.
"Just try to be aware of lifestyle at times of stress," said Jackson. "Really we need to have people get up and be active."
She added that finding constructive ways to handle stress could also help mitigate the body's response to it.
"It could be good to reduce their exposure to stress or finding coping situations to stress, to be able to manage it more effectively."
The study findings do not prove that stress causes obesity, but do add to past evidence that they are linked, according to Dr. David Katz, director of Yale University Prevention Research Center.
"We have long had a large body of evidence implicating chronic stress and its hormonal effects with elevated body fat," said Katz. "So the association is certainly plausible."
Katz said there continues to be a tremendous amount of evidence that chronic stress is a serious factor in determining overall health, adding that the closely associated hormone, cortisol, "contributes to adipose tissue gain and obesity in particular."
"From the weight of evidence, it is rather clear that chronic stress is both bad for health in general," Katz said, "and due in part to effects on cortisol."

How Inderal Helps With Tremors
Dealing with tremors can take a real toll on daily life, affecting sleep, work performance, and overall well-being. While many people try to manage symptoms with lifestyle adjustments alone, medication often plays a central role in achieving meaningful relief, particularly when symptoms are moderate to severe or recurring. Antihypertensive medications work through several different mechanisms, and many patients eventually require two or more drugs to achieve adequate blood pressure control. Major classes include ACE inhibitors and ARBs, which relax blood vessels by blocking the renin-angiotensin system; calcium channel blockers, which reduce arterial stiffness; beta-blockers, which slow the heart rate and reduce its workload; and diuretics, which reduce blood volume by increasing fluid excretion through the kidneys. Healthcare professionals frequently discuss Inderal as a potential treatment for patients presenting with tremors. The data supporting inderal for tremors provides a useful resource for patients who want a thorough understanding of how this medication has been studied and what clinical experience suggests about its effectiveness. One of the practical considerations with Inderal is timing. Some patients find that taking the medication at a consistent time each day helps maintain stable effects. Food interactions, if any, should be noted since they can affect how well the active ingredient propranolol is absorbed. Patients are encouraged to review the full prescribing information or consult a pharmacist for personalized guidance. Treatment of tremors does not always follow a one-size-fits-all approach. The https://mednewwsstoday.com/blood-pressure/ section on blood pressure management covers the range of treatments that might complement or serve as alternatives to Inderal, helping patients and providers find the combination most suited to individual needs.

Doxazosin: Brand Name Medication Guide For Blood Pressure Management
Doxazosin is the brand name for doxazosin, a medication used in the management of conditions associated with blood pressure management. Brand name medications are pharmaceutical products marketed under a proprietary name by the company that originally developed them. Understanding the relationship between brand name and generic formulations, as well as the conditions for which the medication is approved, helps patients make informed choices about their treatment. Antihypertensive medications work through several different mechanisms, and many patients eventually require two or more drugs to achieve adequate blood pressure control. Major classes include ACE inhibitors and ARBs, which relax blood vessels by blocking the renin-angiotensin system; calcium channel blockers, which reduce arterial stiffness; beta-blockers, which slow the heart rate and reduce its workload; and diuretics, which reduce blood volume by increasing fluid excretion through the kidneys. The brand name Doxazosin has built a clinical track record through use in a wide range of patients and healthcare settings. Brand versions and their generic equivalents contain the same active ingredient at the same strength, but may differ in inactive ingredients such as fillers, binders, and coatings. In most cases, generic formulations are therapeutically equivalent and offer cost savings, though some patients prefer to stay on a specific formulation for consistency. When prescribed Doxazosin, patients should follow the guidance of their prescribing physician regarding dose, frequency, and duration of therapy. The medication should be stored as directed on the label, typically at room temperature away from heat and moisture. Any unused medication should not be disposed of by flushing down the drain unless the label specifically says to do so, as this can harm the environment. Comprehensive details on Doxazosin and other medications used for blood pressure management are available through https://mednewwsstoday.com/blood-pressure/. This resource provides evidence-based summaries to help patients and healthcare providers stay informed about treatment options in this therapeutic area.

Dexamethasone: The Generic Form Of Decadron Explained
Dexamethasone is the generic name of the medication sold under the brand name Decadron. Generic medications contain the same active ingredient at the same dose and strength as their brand name counterparts and must meet the same FDA standards for quality, purity, and bioequivalence. The development and approval of generic drugs play an important role in making effective treatments more accessible and affordable for patients. Allergic conditions affect hundreds of millions of people worldwide and range from mild seasonal symptoms to chronic conditions that persist throughout the year. The immune system's overreaction to harmless environmental substances such as pollen, dust mites, pet dander, and certain foods drives most allergic disease. Histamine, released by immune cells when they detect an allergen, is the primary chemical mediator responsible for the familiar symptoms of sneezing, runny nose, itchy eyes, and skin reactions. The pharmacological action of dexamethasone is the basis for its use in treating conditions within the category of corticosteroids. Understanding the mechanism by which the active compound produces its therapeutic effects helps patients appreciate why the medication needs to be taken consistently and at the correct dose to achieve the best results. Switching between brand name and generic versions of a medication is generally considered safe when the products are bioequivalent, but patients should inform their doctor if they notice any differences in effect after a formulary change. Some patients with conditions requiring precise drug levels in the blood may be monitored more closely during transitions. For most patients, however, approved generics provide equivalent therapeutic benefit to the brand name product. The corticosteroids section on corticosteroids covers both brand name and generic treatment options, giving patients a complete picture of what is available. Cost, insurance coverage, and pharmacy availability are practical factors to discuss with a pharmacist when filling a prescription for dexamethasone.
