Metabolic Syndrome

What is metabolic syndrome?

Metabolic syndrome is the name for a group of risk factors for heart disease, diabetes, and other health problems. You can have just one risk factor, but people often have several of them together. When you have at least three of them, it is called metabolic syndrome. These risk factors include:

• A large waistline, also called abdominal obesity or "having an apple shape." Too much fat around the stomach is a greater risk factor for heart disease than too much fat in other parts of the body.
• Having a high triglyceride level. Triglycerides are a type of fat found in the blood.
• Having a low HDL cholesterol level. HDL is sometimes called the "good" cholesterol because it helps remove cholesterol from your arteries.
• Having high blood pressure. If your blood pressure stays high over time, it can damage your heart and lead to other health problems.
• Having a high fasting blood sugar. Mildly high blood sugar may be an early sign of diabetes.

The more factors you have, the higher your risk for heart disease, diabetes, and stroke is.

Metabolic syndrome has several causes that act together:

• Overweight and obesity
• An inactive lifestyle
• Insulin resistance, a condition in which the body can't use insulin properly. Insulin is a hormone that helps move blood sugar into your cells to give them energy. Insulin resistance can lead to high blood sugar levels.
• Age - your risk goes up as get older
• Genetics - ethnicity and family history

People who have metabolic syndrome often also have excessive blood clotting and inflammation throughout the body. Researchers don't know whether these conditions cause metabolic syndrome or worsen it.

The most important risk factors for metabolic syndrome are:

• Abdominal obesity (a large waistline)
• An inactive lifestyle
• Insulin resistance

There are certain groups of people who have an increased risk of metabolic syndrome:

• Some racial and ethnic groups. Mexican Americans have the highest rate of metabolic syndrome, followed by White and Black people.
• People who have diabetes
• People who have a sibling or parent who has diabetes
• Women with polycystic ovary syndrome (PCOS)
• People who take medicines that cause weight gain or changes in blood pressure, blood cholesterol, and blood sugar levels

Most of the metabolic risk factors have no obvious signs or symptoms, except for a large waistline.

Your health care provider will diagnose metabolic syndrome based on the results of a physical exam and blood tests. You must have at least three of the risk factors to be diagnosed with metabolic syndrome:

• A large waistline, which means a waist measurement of
  • 35 inches or more for women
  • 40 inches or more for men
• A high triglyceride level, which is 150 mg/dL or higher
• A low HDL cholesterol level, which is
  • Less than 50 mg/dL for women
  • Less than 40 mg/dL for men
• High blood pressure, which is a reading of 130/85 mmHg or higher.
• A high fasting blood sugar, which is 100 mg/dL or higher

The most important treatment for metabolic syndrome is a heart-healthy lifestyle, which includes:

• A heart-healthy eating plan, which limits the amount of saturated and trans fats that you eat. It encourages you to choose a variety of nutritious foods, including fruits, vegetables, whole grains, and lean meats.
• Aiming for a healthy weight
• Managing stress
• Getting regular physical activity
• Quitting smoking (or not starting if you don't already smoke)

If making lifestyle changes is not enough, you may need to take medicines. For example, you may need medicines to lower cholesterol or blood pressure.

The best way to prevent metabolic syndrome is through the heart-healthy lifestyle changes.

Migraine

What are migraines?

Migraines are a recurring type of headache. They cause moderate to severe pain that is throbbing or pulsing. The pain is often on one side of your head. You may also have other symptoms, such as nausea and weakness. You may be sensitive to light and sound.

Researchers believe that migraine has a genetic cause. There are also a number of factors that can trigger a migraine. These factors vary from person to person, and they include:

• Stress
• Anxiety
• Hormonal changes in women
• Bright or flashing lights
• Loud noises
• Strong smells
• Medicines
• Too much or not enough sleep
• Sudden changes in weather or environment
• Overexertion (too much physical activity)
• Tobacco
• Caffeine or caffeine withdrawal
• Skipped meals
• Medication overuse (taking medicine for migraines too often)

Some people have found that certain foods or ingredients can trigger headaches, especially when they are combined with other triggers. These foods and ingredients include:

• Alcohol
• Chocolate
• Aged cheeses
• Monosodium glutamate (MSG)
• Some fruits and nuts
• Fermented or pickled goods
• Yeast
• Cured or processed meats

About 12% of Americans get migraines. They can affect anyone, but you are more likely to have them if you:

• Are a woman. Women are three times more likely than men to get migraines.
• Have a family history of migraines. Most people with migraines have family members who have migraines.
• Have other medical conditions, such as depression, anxiety, bipolar disorder, sleep disorders, and epilepsy.

There are four different phases of migraines. You may not always go through every phase each time you have a migraine.:

• Prodome. This phase starts up to 24 hours before you get the migraine. You have early signs and symptoms, such as food cravings, unexplained mood changes, uncontrollable yawning, fluid retention, and increased urination.
• Aura. If you have this phase, you might see flashing or bright lights or zig-zag lines. You may have muscle weakness or feel like you are being touched or grabbed. An aura can happen just before or during a migraine.
• Headache. A migraine usually starts gradually and then becomes more severe. It typically causes throbbing or pulsing pain, which is often on one side of your head. But sometimes you can have a migraine without a headache. Other migraine symptoms may include
• Increased sensitivity to light, noise, and odors
• Nausea and vomiting
• Worsened pain when you move, cough, or sneeze
• Postdrome (following the headache). You may feel exhausted, weak, and confused after a migraine. This can last up to a day.

Migraines are more common in the morning; people often wake up with them. Some people have migraines at predictable times, such as before menstruation or on weekends following a stressful week of work.

To make a diagnosis, your health care provider will:

• Take your medical history
• Ask about your symptoms
• Do a physical and neurological exam

An important part of diagnosing migraines is to rule out other medical conditions which could be causing the symptoms. So you may also have blood tests, an MRI or CT scan, or other tests.

There is no cure for migraines. Treatment focuses on relieving symptoms and preventing additional attacks.

There are different types of medicines to relieve symptoms. They include triptan drugs, ergotamine drugs, and pain relievers. The sooner you take the medicine, the more effective it is.

There are also other things you can do to feel better:

• Resting with your eyes closed in a quiet, darkened room
• Placing a cool cloth or ice pack on your forehead
• Drinking fluids

There are some lifestyle changes you can make to prevent migraines:

• Stress management strategies, such as exercise, relaxation techniques, and biofeedback, may reduce the number and severity of migraines. Biofeedback uses electronic devices to teach you to control certain body functions, such as your heartbeat, blood pressure, and muscle tension.
• Make a log of what seems to trigger your migraines. You can learn what you need to avoid, such as certain foods and medicines. It also help you figure out what you should do, such as establishing a consistent sleep schedule and eating regular meals.
• Hormone therapy may help some women whose migraines seem to be linked to their menstrual cycle
• If you have obesity, losing weight may also be helpful

If you have frequent or severe migraines, you may need to take medicines to prevent further attacks. Talk with your health care provider about which drug would be right for you.

Certain natural treatments, such as riboflavin (vitamin B2) and coenzyme Q10, may help prevent migraines. If your magnesium level is low, you can try taking magnesium. There is also an herb, butterbur, which some people take to prevent migraines. But butterbur may not be safe for long-term use. Always check with your health care provider before taking any supplements.

Movement Disorders

Movement disorders are neurologic conditions that cause problems with movement, such as:

• Increased movement that can be voluntary (intentional) or involuntary (unintended)
• Decreased or slow voluntary movement

There are many different movement disorders. Some of the more common types include:

• Ataxia, the loss of muscle coordination
• Dystonia, in which involuntary contractions of your muscles cause twisting and repetitive movements. The movements can be painful.
• Huntington's disease, an inherited disease that causes nerve cells in certain parts of the brain to waste away. This includes the nerve cells that help to control voluntary movement.
• Parkinson's disease, which is a disorder that slowly gets worse over time. It causes tremors, slowness of movement, and trouble walking.
• Tourette syndrome, a condition that causes people to make sudden twitches, movements, or sounds (tics)
• Tremor and essential tremor, which cause involuntary trembling or shaking movements. The movements may be in one or more parts of your body.

Causes of movement disorders include:

• Genetics
• Infections
• Medicines
• Damage to the brain, spinal cord, or peripheral nerves
• Metabolic disorders
• Stroke and vascular diseases
• Toxins

Treatment varies by disorder. Medicines can cure some disorders. Others get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms and relieve pain.

Multiple Sclerosis

Multiple sclerosis (MS) is a nervous system disease that affects your brain and spinal cord. It damages the myelin sheath, the material that surrounds and protects your nerve cells. This damage slows down or blocks messages between your brain and your body, leading to the symptoms of MS. They can include:

• Visual disturbances
• Muscle weakness
• Trouble with coordination and balance
• Sensations such as numbness, prickling, or "pins and needles"
• Thinking and memory problems

No one knows what causes MS. It may be an autoimmune disease, which happens when your immune system attacks healthy cells in your body by mistake. Multiple sclerosis affects women more than men. It often begins between the ages of 20 and 40. Usually, the disease is mild, but some people lose the ability to write, speak, or walk.

There is no specific test for MS. Doctors use a medical history, physical exam, neurological exam, MRI, and other tests to diagnose it. There is no cure for MS, but medicines may slow it down and help control symptoms. Physical and occupational therapy may also help.

Muscular Dystrophy

What is muscular dystrophy (MD)?

Muscular dystrophy (MD) is a group of more than 30 genetic diseases. They cause weakness of the muscles. Over time, the weakness gets worse and can cause trouble walking and doing daily activities. Some types of MD can also affect other organs.

There are many different types of MD. Some of the more common types include:

• Duchenne muscular dystrophy, which is the most common childhood form. It is severe and affects boys more often than girls. The symptoms usually start between ages 3 and 6.
• Becker muscular dystrophy, which is similar to Duchenne but is less severe and gets worse more slowly. It often starts in the teenage years.
• Congenital muscular dystrophies, which are present at birth or before age 2. They can be mild or severe.
• Facioscapulohumeral muscular dystrophy, which often starts in the teenage years. At first, it affects the muscles of the face, shoulders, and upper arms.

Each of the types of MD can be different in many ways, such as:

• Who is more likely to get them
• Which muscles they affect
• When they appear, such as in infancy, childhood, middle age, or later
• What the symptoms are
• How serious the symptoms are
• How quickly they get worse
• Whether they run in families
• Whether they affect other organs

Even within the same type of MD, people can have different symptoms.

MD is genetic, meaning that it caused by a change in one or more genes. Gene changes are also called gene variants or mutations. The gene changes in MD affect proteins that strengthen and protect muscles.

There are different gene changes that cause each type of MD. And sometimes people who have the same type of MD can have different gene changes.

Muscular dystrophy can run in families, or you can be the first in your family to have a muscular dystrophy.

To find out if you or your child has MD, your health care provider may use:

• A medical and family history
• A physical exam
• Blood and urine tests, including genetic tests and tests for certain enzymes that may be released by damaged muscles
• Muscle biopsies
• Electromyography and nerve conduction studies to find out if muscles are responding the right way to nerve signals
• Heart testing, such as an electrocardiogram (EKG), since some types of MD can cause heart problems
• Exercise tests to measure muscle strength and breathing and detect any increased rates of certain chemicals following exercise
• Imaging tests such as an MRI to look at muscle quality and bulk and measure fatty replacement of muscle tissue

There is no cure for muscular dystrophy. Treatment can help with the symptoms and prevent complications. It usually includes a combination of therapies, such as:

• Physical therapy to help keep muscles flexible and strong
• Occupational therapy to relearn lost motor skills and learn ways to work around weakened muscles
• Respiratory care, such as breathing exercises, oxygen therapy, and ventilators
• Speech therapy to help with speech and swallowing problems
• Assistive devices, such as wheelchairs, splints and braces, and walkers
• Medicines to help delay damage to muscles or minimize the symptoms of MD
• Surgery to treat some of the conditions associated with MD, such as heart problems, scoliosis, and cataracts
