Dehydration Affect The Human Heart

Hypothyroidism decreases the heart rate. This is because the body functions slow down. When the body functions slow down, the heart doesn't

There are many factors that can affect your heart rate. Some factors that can speed up or slow down the heart rate is stress, illness, sounds, medication, exercise, etc. For example, with

Diastolic dysfunction is a problem with the ventricle’s ability to relax and fill. Mixed systolic and diastolic dysfunction is a combination of the two defects (Williams and Hopper).

The first signs of dehydration will be thirst, this is your body telling you to get some water that the supply is already low. Moisture will be drawn from the mouth and skin making both dry. This will happen internally too taking water from the body can lead to muscle and stomach gramps. Urination will become less frequent and in little volume because there is little water to spare. The urine will be dark and could smell another sign that water levels ae too low. Being dehydrated will affect the rate you metabolize calories and fuel the body. Depending on age, sex and muscle to fat ratio will affect the rate any given individual will burn calories. I personally have a really high meetabolizem and can eat a lot before seeing changes to my weight. However if I were to become dehydrated the rate of burning calories will slow down making me sluggish. When the body has plenty of water the rate calories are burned stays accelerated ready to fuel the body. In reality staying hydrated will help you loose wait because even at rest your body is using energy and if you are hydrated it will use more energy meaning more calories and cutting

An example of when a sports person becomes dehydrated would be a running race. Runners need to run at their highest level this means that they are using up their energy and becoming dehydrated. This means that you will become fatigued and lack in strength while performing. This can make you slow down or sometimes stop because you can’t last that long. This effects your performance in the race and can cause you to lose the race.

Congestive Heart Failure is when the heart's pumping power is weaker than normal. It does not mean the heart has stopped working. The blood moves through the heart and body at a slower rate, and pressure in the heart increases. This means; the heart cannot pump enough oxygen and nutrients to meet the body's needs. The chambers of the heart respond by stretching to hold more blood to pump through the body or by becoming more stiff and thickened. This only keeps the blood moving for a short while. The heart muscle walls weaken and are unable to pump as strongly. This makes the kidneys respond by causing the body to retain fluid and sodium. When the body builds up with fluids, it becomes congested. Many conditions can cause heart

If the heart beats too fast, too slow or irregularly, it may not be able to pump enough blood to all of the body.

Heart failure is mostly caused by other medical conditions that weaken the heart. These include coronary artery disease, hypertension,

However, it is imperative, before exploring the impact of food on the heart to briefly understand what the hearts job is. The hearts duty is to pump blood around ones body, de-oxygenated blood enters the heart from the inferior and the superior vena cava, this blood then enters the right atrium where the valve pushes out to the right ventricle. From here, the blood goes through individuals pulmonary artery to get oxygen from the lungs. The blood re-enters the heart as oxygenated blood and goes to the pulmonary veins and into the left atrium, this blood is then transferred to the right ventricle. Finally the oxygenated blood leaves the heart from the aorta and the cycle continues. Many things affect the human heart rate such as exercise, illness, stress , eating and many

Well, according to Dr.Ananya Mandal of the News Medical, “dehydration is a condition that results when the body loses more water than it takes in. This imbalance disrupts the usual levels of salts and sugars present in the blood, which can interfere with the way the body functions”. The main reasons for dehydration are the lost of too much fluid in our body when we work and the second is by disease like diabetes. For an instance, work, diseases and prescription are also the cause for the dehydration. You just need to work a little while and you are already on the way to the dehydration. When you have diabetes, you will have high blood sugar level, urination and fluid loss will lead to it as well. Simple as that, fluid lost inside, diseases, prescription are mainly the cause for the

The major causes of diastolic heart failure are hypertension-induced myocardial hypertrophy and myocardial ischemia-induced ventricular transformation (coronary artery disease). Hypertrophy and ischemia cause a decreased ability of the myocytes to actively pump calcium from the cytosol, resulting in impaired relaxation. Some of the other causes are aortic valvular disease and cardiomyopathies. Diabetes can also lead to diastolic heart failure (Huether and McCune 2012). Other risk factors for this disease are chronic kidney disease, obstructive sleep apnea, and older age. There are two types of the heart failure: systolic heart failure and diastolic heart failure. In systolic heart failure, the left ventricle has difficulty contracting and ejecting blood into the circulation, which causes reduced left ventricular fraction. On the other hand, diastolic heart failure has a slow and delayed relaxation and increased chamber rigidity, which then causes inadequate filling of blood and

There are several causes to elderly dehydration, which can be broken down into four groups: physiological factors, psychological factors, functional impairments, and mechanical impairments. (Hamilton, 2001) The physiological factors are: natural

The body needs a certain amount of cardiac output to maintain its basic functions. In congestive heart failure the body needs more output than the heart can put out. To make up for the lack of cardiac output, the heart sends all of its output to the essential organs such as the brain and lungs. It neglects to send as much blood to the extremities. This is why in congestive heart failure patents, edema is usually present. Fatigue results from the heart having to work extra hard to send blood to only a few essential organs. This is why fatigue is considered the first symptom of congestive heart failure. Congestive Heart Disease can happen on either side of the heart, or it can effect both sides. When the heart cannot keep up with what the body needs capillary pressure increases. When this capillary pressure increases it causes sodium to build up, and the body does not excrete the

The literature on the effects of exercise of cardiac output maintains the idea that exercise should affect cardiac output- pulse rate, systolic blood pressure, diastolic blood pressure, QRS-pulse lag, P-T and T-P intervals, because of increased heart rate. For our experiment, we tested this theory by measuring our cardiac output before and after some rigorous exercise. We measured the individual cardiac output and then combined the data to compose a class-wide data average. We compared the results of the experiment to what we expected, which was that exercise does affect our heart. Our data from this experiment supported the notion that exercise does, in fact, change cardiac output.

The article I chose talks about the effects of dehydration on the body. The first example, put simply, is if a human loses 2% of their body mass in water, then your kidneys will send less water to the bladder and stop producing sweat. This follows the first rule of logic because if the body did not lose that amount of water, then the body would function normally. It follows the second rule of logic because these are the results of scientific studies, meaning that these are the effects observed in most, if not all, cases. All events included are necessary for the result. The second example I chose states that if the human body sweats less, then the internal body temperature will increase. This follows the first rule of cause and effect because
