Causes Of High Blood Pressure
High blood pressure is of 2 types and as such the causes differ from each other
1. Primary Hypertension
It is even known as essential hypertension and it occurs over a period with no particular cause. The majority of people have this kind of high blood pressure. These causes include
- Genes, few people by birth are prone to this and it could be due to genetic abnormalities or gene mutations.
- Physical changes, if the body goes through some changes a person may start to experience this condition.
- The environment and an unhealthy lifestyle too can lead to this condition. Obesity is one result of an unhealthy lifestyle.
2. Secondary Hypertension
- Problems of the adrenal gland
- Few types of endocrine tumors

These changes to your resting heart rate provide a peek into what is going on with your body. These three surprising things that alter your resting heart rate provide insight into how changes in your health affect this easily measured biometric.
The Dangers Of Dehydration
Here in the South, July and August are two of the most sweltering months and it is important to take care of our bodies during times of extreme heat. One of the most common summertime dangers is dehydration. It is essential to remember that dehydration is dangerous not only to people, but pets and animals as well.
A common mistake many people make is grabbing an ice-cold soda or energy boosting drink instead of water, but these beverages can actually cause you to become even more dehydrated. Listed below are ten dangers of dehydration that you should be aware of for yourself, loved ones, and pets:
1. Muscle Cramps– You dont have to be an athlete to get muscle cramps. Those who are minimally active and drink insufficient fluids are equally prone to cramps. Dehydration causes hypersensitivity and involuntary contraction of muscles.
2. Depression– The brain requires 85% water – more than any other organ in the body. Water deficiency in brain cells can result in an immediate cut down of the brains energy supply, which leads to fatigue, lethargy, and depression.
3. Constipation– After food is eaten, it is broken down in the small intestine and the non-essential portion of the food gets converted to waste. Dehydration causes the intestinal cells to extract water from the food waste in the intestines, causing the waste to become hard, leading to constipation.

When Changes In Heart Rhythms Warrant A Physicians Attention
Though most fluctuations in heart rhythms will likely be harmless, there are times your first response should be to seek medical advice.
- Your symptoms are sudden and abnormal. If theres a clear first time that you notice a rhythm change in your heart, its a good idea to alert your doctor, Anderson says. You should also call your doctor when a change in heart rhythms corresponds to chest pain, losing consciousness or a prolonged sense that you might pass out. Likewise, contact a medical professional if a rhythmic abnormality persists.
- Your history involves other heart issues. If you were born with a malformation if youve had heart surgery if youve had a heart attack or long-standing, untreated high blood pressure or if there is something otherwise abnormal with your heart and you notice abnormal heart rhythms, you should see your doctor.
- Your family history puts you at increased risk. Your doctor may ask you to attend more closely to changes in your heart rhythms if your family has a history of heart disease or sudden death.
Fluids Matter To The Heart
Dehydration causes your blood volumethe amount of blood circulating throughout your bodyto decrease. As a result, sodium levels in the blood increases, thickening the blood and making it harder for it to circulate. In turn, this taxes your heart muscles even more. The result: Your heart rate rises and blood pressure may drop. Its amazing, because you can actually see on an echocardiogram, an ultrasound of the heart, if someones dehydrated, Dr. Steinbaum says.
In someone with heart issues, including intermittent cardiac arrhythmias such as atrial fibrillation, dehydration can cause changes in heart function as well. Significant shifts in fluid levels in the heart chambers can theoretically trigger the rhythm disturbance, although this is rare, says Alon Gitig, M.D., a cardiologist and director of cardiology at Mount Sinai Doctors Westchester and assistant professor of medicine at Icahn School of Medicine at Mount Sinai in New York City. Dr. Gitig says avoiding dehydration is most important for cardiac patients with a tendency toward low blood pressure. Many medications commonly used in management of congestive heart failure, coronary artery disease, or arrhythmias have the potential to lower blood pressure, he explains. This effect is exacerbated if the arteries and veins are circulating less blood volume.

Dehydration In Elderly People: Risks Warning Signs And Prevention Tips
Did you know that the consequences of dehydration in elderly adults are often seriousmore so than in younger people? Seniors also have more risk factors for becoming dehydrated. But here’s the good news: Dehydration can be easily prevented. Awareness is the first step in avoiding the health problems that can be caused by a lack of fluids.
But many people don’t realize just how problematic dehydration can be for older adultsand how common it really is. Take a look at these facts:
- According to a review article in e-SPEN, the European e-Journal of Clinical Nutrition and Metabolism, one study showed that about 31 percent of long-term care patients were found to be dehydrated.
- Treating elderly people who are hospitalized for dehydration costs the medical system about $1.36 billion annually, according to an article in Nutrition and Healthy Aging.
- Dehydrated patients are six times more likely to die in the hospital than patients who are not dehydrated, according to a study in Age and Ageing.
This article explains why older people are at greater risk for becoming dehydrated. It also lists the consequences of dehydration in the elderly. As well, you’ll learn how to spot the warning signs of dehydration and discover what to do if you or a loved one experiences symptoms.
Dehydration And Low Blood Pressure
Low blood pressure is when your blood pressure reading is lower than 90/60 mm Hg. Dehydration can cause low blood pressure due to a decrease in blood volume.
Blood volume is the amount of fluid thats circulating in your blood vessels. Maintaining a normal blood volume is necessary for blood to be able to adequately reach all of the tissues of your body.
When youre very dehydrated, your blood volume can decrease, leading to a drop in blood pressure.
When blood pressure drops too low, your organs wont receive the oxygen and nutrients they need. You could potentially go into shock.

“If you are on a protein-rich diet, you need to really work to increase the amount of water-carrying veggies in your diet to offset the potential dehydrating effect of protein,” Dr. Bush says.
When To Contact A Doctor
If the rate or rhythm of the heartbeat becomes irregular or is causing distressing symptoms, it is important to seek medical attention.
Even if there does not appear to be any danger, a doctor can provide assistance in reducing the risk of complications.
If a person is experiencing the following symptoms, all of which are symptoms of a heart attack, someone needs to call 911:
- chest pain
Why Is My Heart Racing
Considering the incredible job your heart doeskeeping you alive by pumping blood to provide your body with the oxygen and nutrients it needsyou probably dont often think about how hard it works every second of the day. To be precise, your heart beats from 60 to 100 beats a minute. If your heart beats more than 100 times per minute, its known as tachycardia. It might sound serious, but its unlikely to be a sign of a heart attack. Here are nine possible reasons your heart is racing.
Dehydration Impacts Heart Rate And Performance
There has been some controversy lately over the effects of dehydration on health and performance in athletes. Its consequences for performance were investigated in a recent Journal of Strength and Conditioning Research study.
The researchers performed a review of the scientific literature to investigate the effects of hydration status on heart rate. They chose only studies that included comparisons of dehydration to euhydration , and conducted research specifically in the heat. The search resulted in twenty studies to include in the review.
Naturally, the idea here is that when exercise is conducted in the heat, athletes lose water, mainly through sweat. This may also apply to other sports in which water is cut to achieve a specific weight class. This topic has actually come under debate, and some believe that perhaps the consequences of dehydration have been overhyped.
The researchers chose to analyze heart rate for a couple reasons. First, heart rate is a decent gauge of health, fitness, and stress. The heart responds to a variety of physical and psychological stimuli, and the way it responds has a great deal to do with a persons wellbeing. Second, measuring heart rate is a simple test that anyone can perform and is easy for everyone to understand. Many kinds of tests require lab conditions, such as VO2 max testing, but measuring heart rate only requires a clock.

Why Dehydration Is More Common Among Seniors
Maintaining a healthy balance of water and electrolytes can be an even more complex process for seniors than it is for younger people. As a result, older people are more likely to get dehydrated. And the complications of dehydration in the elderly can be more serious.
According to an article in Frontiers in Molecular Biosciences, dehydration is one of the top 10 reasons for seniors to be hospitalized. And for hospitalized seniors, dehydration can lead to longer stays in intensive care units, increased hospital readmissions, and more placements in long-term care facilities.
Why does the risk of dehydration increase with age? Older adults are prone to dehydration because they can experience several health or lifestyle conditions that lead to low fluid levels. Many seniors experience at least one of the following risk factors:
Weird Things That Can Mess With Your Heartbeat
Learn the top triggers of heart palpitations, plus what to do about each one.
A few weeks ago I thought I was having a heart attack. My morning started out normal: I woke up at my usual hour, feeling what I thought was a little bit of tiredness. But as I went about my morning routine, things grew scary. I broke out in a cold sweat as I brushed my teeth. My skin turned white as paper. And then, scariest of all: my heart was pounding like crazy. As a health writer I know these aren’t textbook signs of a heart attack, but I also know that dangerous cardiovascular events in women can be more subtle than those in men.
Later that day I went to urgent care, but an EKG and blood tests showed nothing out of the ordinary. Turns out my heartbeat went haywire as a result of a side effect from a medication. The technical term for this: heart palpitations, which can be brought on by many things.
When a person says theyre having heart palpitations theyre referring to a sensation of their heart beating differently. Or they may simply have an awareness of their heart beating, explains Shephal Doshi, MD, director of cardiac electrophysiology at Providence Saint Johns Health Center in Santa Monica, California.

How Can Dehydration Be Prevented
The following tips can help keep your body’s fluid balance in check:
Drink lots of fluids. The amount of fluid needed each day to stay hydrated depends on your health, treatment, and lifestyle. Ask your doctor how much water you should drink. If you dislike plain water, try drinking flavored water or adding a slice of lemon. Other fluids can also help, including milk, low-sugar juice, and caffeine-free tea.
Remember to avoid foods and drinks that may contribute to dehydration. Avoid alcohol. Choose drinks with low sugar and low or no caffeine. Water is often a better choice than fruit juice, soda, or coffee.
Eat foods with high water content. Drinking water is the best way to hydrate. But many foods contain water and can also help replenish lost fluids. Choose foods such as lettuce , watermelon , and broccoli . Soup, popsicles, and yogurt also have high water content.
Manage side effects. Cancer treatment can cause nausea, vomiting, or diarrhea. Talk with your health care team about ways to prevent or reduce these side effects and any concerns you have about dehydration.
Monitor your environment and activity. Do not wait to drink water or other fluids. Make a conscious effort to drink regularly. Drink more often before you exercise and before you go outside in hot weather. During an illness or if you are feeling unwell, be proactive and drink water to stay hydrated in order to help your recovery.
Signs Of Severe Dehydration And How To Treat It
Chances are you suffer from chronic dehydration. After all, statistics show that over 75% of Americans do. Thats close to 246 million people.
While dehydration is common, it doesnt look the same in everyone. Its signs and symptoms can vary depending on the person affected, as well as the severity of the condition. Infants and children, as well as the elderly, are at increased risk for dehydration. Plus, what doctors classify as a mild to moderate case of dehydration varies from severe dehydration.
Catching it early is key to proper dehydration treatment and prevention of a more serious case that could become life-threatening.

What Does Water Do For Your Body
Between about 55% to about 78% of your body is made of water. Newborn babies are about 78% water, a year-old baby is 65%, adult men are about 60% and adult women are about 55%. Your brain is made up of 73% water, and so is your heart. Your bones are 31% water, muscles and kidneys are 79% and your skin is 64%. A whopping 83% of water makes up your lungs.
- Aid digestion and get rid of waste.
- Work your joints. Water lubricates them.
- Make saliva .
- Balance your bodys chemicals. Your brain needs it to create hormones and neurotransmitters.
- Deliver oxygen all over your body.
- Cushion your bones.
- Regulate your body temperature.
Act as a shock absorber for your brain, your spinal cord and, if youre pregnant, your fetus.
Water is important to your body, especially in warm weather. It keeps your body from overheating. When you exercise, your muscles generate heat. To keep from burning up, your body needs to get rid of that heat. The main way the body discards heat in warm weather is through sweat. As sweat evaporates, it cools the tissues beneath. Lots of sweating reduces the body’s water level, and this loss of fluid affects normal bodily functions. Drink water!
How Do You Calm A Fast Heartbeat
If you think youre having an attack, try these to get your heartbeat back to normal: Breathe deeply. It will help you relax until your palpitations pass. Splash your face with cold water. It stimulates a nerve that controls your heart rate. Dont panic. Stress and anxiety will make your palpitations worse.

How Much Fluid Do I Need
Your body needs different amounts of water before, during, and after exercise.
- Before exercise, you should drink one cup of water at least four hours before you start exercising.
- During exercise, you should drink 120-150 ml of water every 10-15 minutes.
- After exercise, you should drink enough water to double the amount of water your body lost during exercise.
What Hydration Means
The amount of water you need depends on a range of factors, such as climatic conditions, your health, your clothing, your exercise intensity and duration. So, being well hydrated will differ per person and situation.
As a guide, you probably need more fluid if:
- you have certain medical conditions, such as diabetes or heart disease
- you have cystic fibrosis, which means you have a high concentration of sodium in your sweat
- you are using a medication that can act as a diuretic, causing your body to lose more fluid
- you have a bigger body size
- you are fit
- you are doing vigorous exercise
- you are active in hot or humid conditions.
Thirst isnt the best indicator that you need to drink. In fact, if you feel thirsty, you are probably already dehydrated.
A good test of dehydration is the colour of your urine. If its pale and clear it means youre well hydrated. The darker it is, the more fluid you need to drink.
Another sign of dehydration is a lack of sweat during vigorous activity, when you expect to sweat. No sweating is a sign that youre both dehydrated and probably suffering heat exhaustion.
