How does muscular dystrophy affect the skeletal system?

How does muscular dystrophy affect the skeletal system?

Muscular dystrophy (MD) refers to a group of more than 30 genetic diseases that cause progressive weakness and degeneration of skeletal muscles used during voluntary movement.

How does muscular dystrophy affect the body?

Muscular dystrophy is a group of inherited diseases that damage and weaken your muscles over time. This damage and weakness is due to the lack of a protein called dystrophin, which is necessary for normal muscle function. The absence of this protein can cause problems with walking, swallowing, and muscle coordination.

How does muscular dystrophy affect the digestive system?

In the upper digestive tract, dysphagia, heartburn, regurgitation and dyspepsia are the most common complaints, while in the lower tract, abdominal pain, bloating and changes in bowel habits are often reported. Digestive symptoms may be the first sign of dystrophic disease and may precede the musculo-skeletal features.

How does muscular dystrophy affect the immune system?

A hyperactive immune system can lead to inflammation and autoimmune disorders. Muscular dystrophy is a group of inherited diseases that lead to progressive muscle weakening and loss of muscular control. In some cases, the immune system can attack diseased muscle and damage tissue.

How does muscular dystrophy affect development?

Children with Duchenne MD may need a wheelchair by the time they’re 12 years old, as their muscles weaken and they lose the ability to walk. They can also develop scoliosis, where the spine begins to curve sideways. This can lead to one shoulder or hip being higher than the other.

How does muscular dystrophy affect the brain?

The molecular missteps that disrupt brain function in the most common form of adult-onset muscular dystrophy have been revealed in a new study. Myotonic dystrophy is marked by progressive muscle wasting and weakness, as well as sleepiness, memory problems, and mental retardation.

How does muscular dystrophy affect the heart?

Both the Duchenne and Becker forms of muscular dystrophy are associated with a heart condition called cardiomyopathy. This form of heart disease weakens the cardiac muscle, preventing the heart from pumping blood efficiently.

What are some risk factors of muscular dystrophy?

If the genetic makeup is there and active in specific chromosomes in your body, you may get muscular dystrophy….Lifestyle Risk Factors

• Being underweight as measured by the body mass index.
• Having poor lung function.
• Having a high blood concentration of a protein linked to cardiac damage.

Who is most affected by muscular dystrophy?

Muscular dystrophy occurs in both sexes and in all ages and races. However, the most common variety, Duchenne, usually occurs in young boys. People with a family history of muscular dystrophy are at higher risk of developing the disease or passing it on to their children.

Can muscular dystrophy cause constipation?

Muscular dystrophy has been traditionally associated with common gastrointestinal symptoms such as reflux, constipation, and dysphasia.

What disease causes muscle damage?

Myositis (my-o-SY-tis) is a rare type of autoimmune disease that inflames and weakens muscle fibers. Autoimmune diseases occur when the body’s own immune system attacks itself. In the case of myositis, the immune system attacks healthy muscle tissue, which results in inflammation, swelling, pain, and eventual weakness.

What disease causes muscles to harden?

Stiff-person syndrome (SPS) is a rare acquired neurological disorder characterized by progressive muscle stiffness (rigidity) and repeated episodes of painful muscle spasms. Muscular rigidity often fluctuates (i.e., grows worse and then improves) and usually occurs along with the muscle spasms.

How are muscles affected by muscular dystrophy ( MD )?

These disorders vary in age of onset, severity, and pattern of affected muscles. All forms of MD grow worse as muscles progressively degenerate and weaken. Many individuals eventually lose the ability to walk. Some types of MD also affect the heart, gastrointestinal system, endocrine glands, spine, eyes, brain, and other organs.

What was the cause of muscular dystrophy in the 1850s?

At that time the symptoms were thought to be signs of tuberculosis. In the 1850s, descriptions of boys who grew progressively weaker, lost the ability to walk, and died at an early age became more prominent in medical journals.

Are there any advances in muscular dystrophy research?

Advances in basic research are essential to the basic understanding of each type of MD. While many genes that cause muscular dystrophy still remain to be identified, advances in gene sequencing has aided the identification of genes that may be involved for most types of muscular dystrophy.

How does the skeletal system contribute to homeostasis?

Skeletal muscles contribute to maintaining temperature homeostasis in the body by generating heat. Muscle contraction requires energy and produces heat as a byproduct of metabolism. All types of muscle produce heat, but because of the large amount of skeletal muscle present in the body, skeletal muscle contributes most greatly to heat production.
