The Liver And Its Functions

The liver is a very vital part of our body, we cannot survive without it, in today’s post, I will be looking at the liver and its functions.

What Is The Liver 

The liver is a very important organ in the body, it weighs about 3 lbs reddish-brown in color and has a rubbery feel to the touch, it sits on the right side of the belly protected by the rib cage.

The liver has two sections refer to as the right and left lobes, The gallbladder, and parts of the pancreas and intestines are right under the liver

Musculoskeletal Disease in seniors. (Bone Density)

In this post, I will be looking at bone density one of the Musculosketial diseases that can affect us.

Bone is made mostly of collagen, a protein that is woven into a flexible framework.

Bone also contains calcium phosphate and calcium carbonate, minerals that add strength and harden the framework.

The combination of calcium and collagen gives the bone its strength and flexibility.

The flexibility (or ability to withstand stress) of the bone protects it from breaking.

Bone is strong because of calcium, but bone also acts as a storehouse for calcium.

In fact, more than 99% of the body’s calcium is contained in the bones and teeth. The remaining 1% is in the blood.

Diabetic related diseases

I will be looking at diseases that are diabetic related, it is said that no one dies from diabetes. But it is the effect that diabetes has on the body that is dangerous and will cause death.

Diabetes is linked to a host of other health problems. But if care is taken and the diabetes is and you can control your diabetes, then your risk of developing those complications and secondary conditions goes down,” says Karen McDermaid, a diabetes educator in Moosomin, Saskatchewan. These five conditions are the big ones to look out for if you’re prediabetic or have diabetes

What Are Lymphocytes And Why It Is Important To Us

Lymphocyte are cells that is very important to us
What Are Lymphocytes And Why It Is Important To Us

According to Healthline medical online magazine Lymphocytes are one of several types of white blood cells. Each type of white blood cell has a specific function, and they all work together to fight illness and disease.

These white blood cells are an important part of the immune system. They help your body fight antigens which are bacteria, viruses, and other toxins that make you sick. If your doctor says you have a weakened immune system, that means there aren’t enough white blood cells in your bloodstream.

Lymphocytes and how they work

Cells are produced constantly by the bone marrow and these cells l become lymphocytes.

Some of these lymphocytes will enter your bloodstream, but most will move through your lymphatic system.

The lymphatic system is the group of tissues and organs,  that protect your body from infection Theses organs include the spleen, tonsils and lymph nodes.

About a 1/4  of the new lymphocytes remain in the bone marrow and become B cells. The other ¾  of these new lymphocytes travel to your thymus and become T cells 

Most lymphocytes are short-lived, with an average life span of lymphocytes is a week to a few months, but a few live for years, providing a pool of long-lived T and B cells.

These cells account for immunologic “memory,” these memory cells that have been in your body long enough to recognize and “remember” past infections and go into action quickly if you become re-infected with an antigen

lymphocytes are able to bind antigens (foreign substances or microorganisms that the host recognizes as “non self”) and help remove them from the body.  This is done through receptor molecules on their surfaces,

Each lymphocyte bears receptors that bind to a specific antigen. The ability to respond to virtually any antigen comes from the enormous variety of lymphocyte populations that the body contains, each of them with a receptor capable of recognizing a unique antigen.

Lymphocytes move around your body through the lymphatic system, which is part of the circulatory system. Lymph vessels carry clear fluid, including lymphocytes and other white blood cells, throughout your body to fight infection.

What Are T Cell Lymphocytes?

T cell lymphocytes’ continually scan and monitor your cells for infection and the risk of infection.

These T cell lymphocytes also kill cancer cells, and there is a  promising approach to cancer treatment (known as CAR-T therapy) that involves isolating, multiplying and then using a patient’s own T cells to fight particular cancer.

In addition, there is evidence that T cell lymphocytes also can protect you from bacteria by actually capturing and killing the bacteria in question.

What Are B Cell Lymphocytes?

B cell lymphocytes don’t attack and kill cells, viruses or bacteria themselves.

They manufacture proteins called antibodies that actually stick to the surface of invaders, disabling those invaders and spotlighting them for clean up by other parts of your immune system.

Each B cell only produces one specific antibody, But because the body’s huge number of B-cells collectively recognize an almost unlimited number of intruders and produce a tremendous variety of antibodies to fight them.

Like T cell lymphocytes, B cell lymphocytes also are made in your bone marrow. They mature in your spleen.

Lymphocytes do not always behave normally.

In autoimmune disease, for example, T cell lymphocytes mistakenly attack your own tissues, mistaking your cells for foreign an example Celiac disease, which involves an autoimmune attack on the lining of your small intestine.

Scientists aren’t certain what propels T cells to do this.

You also can develop cancer that specifically affects your lymphocytes. This type of cancer is called Hodgkin’s disease or non-Hodgkin lymphoma.

There are several different types of Hodgkin’s disease and non-Hodgkin lymphoma, and the type you have is determined by the type of lymphocytes involved.

Hodgkin’s disease involves only the B cell lymphocytes, for example, while non-Hodgkin lymphoma can involve either the B cell or T cell lymphocytes.

There are over 100 types of autoimmune diseases, we will take a brief look at the more common ones.

Rheumatoid arthritis, a form of arthritis that attacks the joints

Psoriasis, a condition marked by thick, scaly patches of skin

Psoriatic arthritis, a type of arthritis affecting some people with psoriasis

Lupus, a disease that damages areas of the body that include joints, skin and organs

Thyroid diseases, including Graves’ disease, where the body makes too much thyroid hormone (hyperthyroidism), and Hashimoto’s thyroiditis, where it doesn’t make enough (hypothyroidism) of the hormone

Common Autoimmune Disease Symptoms

Despite the varying types of autoimmune disease, many of them share similar symptoms. Common symptoms of autoimmune disease include:

  • Fatigue
  • Joint pain and swelling
  • Skin problems
  • Abdominal pain or digestive issues
  • Recurring fever
  • Swollen glands

Autoimmune Disease Risk Factors

Researchers don’t know what causes autoimmune disease, but several theories point to an overactive immune system attacking the body after an infection or injury. We do know that certain risk factors increase the chances of developing autoimmune disorders, including:

  • Genetics: Certain disorders such as lupus and multiple sclerosis (MS) tend to run in families. Medical Expert Orbai says “Having a relative with an autoimmune disease increases your risk, but it doesn’t mean you will develop a disease for certain,”
  • Weight: Being overweight or obese raises your risk of developing rheumatoid arthritis or psoriatic arthritis. This could be because more weight puts greater stress on the joints or because fat tissue makes substances that encourage inflammation.
  • Smoking: Research has linked smoking to a number of autoimmune diseases, including lupus, rheumatoid arthritis, hyperthyroidism and MS.
  • Certain medications: “Certain blood pressure medications or antibiotics can trigger drug-induced lupus, which is often a more benign form of lupus,” Orbai says. “Our myositis center also discovered that specific medications used to lower cholesterol, called statins, can trigger statin-induced myopathy.

Myopathy is a rare autoimmune disease that causes muscle weakness. Before starting or stopping any medications, however, make sure to talk to your doctor.

Autoimmune Disease and its effects on Your health

Having lupus, rheumatoid arthritis or psoriatic arthritis raises your risk for heart disease. While taking steps to reduce heart disease is always a good idea, it is even more essential if you have one of these conditions.

The need to keep your heart health is very important so have a talk with your doctor about what steps can be taken to keep your heart healthy and strong.

Keeping your blood pressure and cholesterol levels within healthy ranges would be something you can do to encourage heart health. And eating a nutritious diet and exercising regularly can also be beneficial to your health.

Taking these steps can also help reduce the symptoms of autoimmune disease. Orbai admits that making time for healthy living can be hard, given the fast-paced lives that we live, but she insists that finding the balance is key to living with autoimmune disease.

Treating the symptoms of autoimmune disease “It’s something that’s going to involve commitment, and sometimes it’s going to be tough,” she says. “But learning to listen to your body and being smart about what triggers your disease is important. It’s something you do for yourself”

Heart Health Information For Seniors——Make Healthy Choices

Heart Health Information For Seniors

Cardiovascular disease is responsible for almost half of all deaths by non-communicable diseases.

CVD is a name applied to a number of different diseases affecting the heart and blood vessels. Coronary heart disease is a type of CVD that occurs when blood supply to the heart is restricted or blocked (which can, in turn, lead to angina, heart attack, and heart failure).

What is the Heart

The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.

“The tissues of the body need a constant supply of nutrition in order to be active,” said Dr. Lawrence Phillips, a cardiologist at NYU Langone Medical Center in New York. “If [the heart] is not able to supply blood to the organs and tissues, they’ll die.

In humans, the heart is roughly the size of a large fist and weighs between about 10 to 12 ounces (280 to 340 grams) in men and 8 to 10 ounces (230 to 280 grams) in women, according to Henry Gray’s “Anatomy of the Human Body.”

The physiology of the heart basically comes down to “structure, electricity, and plumbing,” Phillips told Live Science.

The human heart has four chambers: two upper chambers (the atria) and two lower ones (the ventricles), according to the National Institutes of Health. The right atrium and right ventricle together make up the “right heart,” and the left atrium and left ventricle make up the “left heart.” A wall of muscle called the septum separates the two sides of the heart.

The Heart Changes With Age

As we age the possibility of developing heart problems increases,

Older people tend to suffer a heart attack, have a stroke, or develop coronary heart disease (commonly called heart disease) and heart failure more than the younger people.

Heart disease can also cause disability, limiting the activity and eroding the quality of life of millions of older people.

A major cause of heart disease in the boomers is the buildup of fatty deposits in the walls of arteries. Fortunately, there are steps that can be taken to delay, lower, or possibly avoid or reverse the risk of fat deposits in the artery walls.

Increased stiffness of the large arteries, called arteriosclerosis, or hardening of the arteries is the most common change due to aging.

Arteriosclerosis is the cause of high blood pressure, which becomes more common as we age.

Because there are several risk factors that cause atherosclerosis, it is not necessarily a normal part of aging.

The building up of plaque inside the walls of your arteries over time hardens and narrows your arteries, and this limits the flow of oxygen-rich blood to your organs and other parts of your body.

Oxygen and blood nutrients are supplied to the heart muscle through the coronary arteries. The blockage of any of these arteries can cause a heart attack or damage to the muscle of the heart.

Plaque builds up in the coronary arteries, which reduces blood flow to your heart muscle. And if not corrected Over time, the heart muscle can become weakened and/or damaged, resulting in heart failure.

There are different things that can cause damage to the heart, alcohol abuse, diabetes high blood pressure and stand for long periods, in the case of long-standing it is best to wear compression socks or stocking and if you suffer from diabetes and high blood pressure keep them under control

There are age-related changes in the electrical system that can lead to a rapid, slowed, or irregular heartbeat (arrhythmias) in this case a pacemaker may be needed to regulate the flow of blood

( see video below).  

      • The chambers of your heart may also increase in size and the heart wall becomes thick, so the amount of blood that a chamber can hold may decrease. The heart may fill more slowly, uncontrolled hypertension over a long period of time is the main cause of increased thickness of the heart wall, which can increase the risk of atrial fibrillation, a common heart rhythm problem in older people.

With increasing age, we may become more sensitive to salt, which may cause an increase in blood pressure and/or ankle or foot swelling (edema).

Other factors, such as thyroid disease or chemotherapy, may also weaken the heart muscle. And if heart disease is also present in your family history, this may increase your risk of heart disease.

Heart disease is caused when the coronary arteries that surround the outside of the heart and supply blood nutrients and oxygen to the heart muscle, are partially or blocked by plaque build-up inside the arteries.

The plaque build-up into the arteries causes less space for blood to flow normally and deliver oxygen to the heart. If the flow of blood to your heart is reduced by plaque buildup or is blocked, and if a plaque suddenly ruptures, it can cause angina (chest pain or discomfort) or a heart attack.

When the heart muscle does not get enough oxygen and blood nutrients, the heart muscle cells will die (heart attack) and weaken the heart, diminishing its ability to pump blood to the rest of the body.

According to the signs of a heart attack are:

Signs Of Heart Attack 

Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts more than a few minutes – or it may go away and then return. It can feel like uncomfortable pressure, squeezing, fullness or pain.

Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.

Shortness of breath. This can occur with or without chest discomfort.

Other signs. Other possible signs include breaking out in a cold sweat, nausea or light-headedness.

Prevent Heart Disease

There are many steps you can take to keep your heart healthy.

On the advice of your doctor, aim to get at least 150 minutes of physical activity each week. Every day is best. It doesn’t have to be done all at once.

Start by doing activities you enjoy—brisk walking, dancing, bowling, bicycling, or gardening, for example. Avoid spending hours every day sitting.

Smoking is the leading cause of preventable death. Smoking adds to the damage to the artery walls. It’s never too late to get some benefit from quitting smoking.

Eat healthily, the dash diet is highly recommended by cardiologists,   (The DASH diet is a dietary pattern promoted by the U.S.-based National Heart, Lung, and Blood Institute to prevent and control hypertension. The DASH diet is rich in fruits, vegetables, whole grains, and low-fat dairy foods; includes meat, fish, poultry, nuts, and beans; and is limited in sugar-sweetened foods and beverages, red meat, and added fats. Wikipedia )

Keep a healthy weight. Balancing the calories you eat and drink with the calories burned by being physically active helps to maintain a healthy weight.

Keep your diabetes, high blood pressure, and/or high cholesterol under control. Follow your doctor’s advice to manage these conditions, and take medications as directed.

Limit stress, in today’s life there is a lot of stress, and unfortunately, it is easy to become overwhelmed by stress

But we can manage stress, like exercise, deep breathing, relaxing your muscles by stretching, take a break, slow down take it easy.
