Hormones

Hormones are your body's chemical messengers. They travel in your bloodstream to tissues or organs. They work slowly, over time, and affect many different processes, including:

• Growth and development
• Metabolism - how your body gets energy from the foods you eat
• Sexual function
• Reproduction
• Mood

Endocrine glands, which are special groups of cells, make hormones. The major endocrine glands are the pituitary, pineal, thymus, thyroid, adrenal glands, and pancreas. In addition, men produce hormones in their testes and women produce them in their ovaries.

Hormones are powerful. It takes only a tiny amount to cause big changes in cells or even your whole body. That is why too much or too little of a certain hormone can be serious. Laboratory tests can measure the hormone levels in your blood, urine, or saliva. Your health care provider may perform these tests if you have symptoms of a hormone disorder. Home pregnancy tests are similar - they test for pregnancy hormones in your urine.

How to Prevent High Blood Pressure

Around half of American adults have high blood pressure (hypertension). Many of those people don't know they have it because there are usually no warning signs. This can be dangerous, because high blood pressure can lead to life-threatening conditions like heart attack or stroke. The good news is that you can often prevent or treat high blood pressure. Early diagnosis and heart-healthy lifestyle changes can keep high blood pressure from seriously damaging your health.

Each time your heart beats, it pumps blood into your arteries (the blood vessels that carry blood from your heart to the tissues and organs in your body). Blood pressure is the force of your blood pushing against the walls of your arteries. Blood pressure is measured as two numbers:

• Systolic pressure (the first and higher number) measures pressure inside your arteries when your heart beats
• Diastolic pressure (the second and lower number) measures the pressure inside your arteries when your heart rests between beats

As an example, a blood pressure reading of 120/80 means a systolic of 120 and a diastolic of 80.

High blood pressure usually has no symptoms. So the only way to find out if you have it is to get regular blood pressure checks from your health care provider. Your provider will use a gauge, a stethoscope or electronic sensor, and a blood pressure cuff. They will take two or more readings at separate appointments before making a diagnosis:

For children and teens, the provider compares the blood pressure reading to what is normal for other kids who are the same age, height, and sex.

Anyone can develop high blood pressure, but there are certain factors that can increase your risk:

• Age. Blood pressure tends to rise with age.
• Race/Ethnicity. High blood pressure is more common in Black adults. They also tend to have higher average blood pressure numbers and get high blood pressure earlier in life.
• Sex. Men are more likely than women to develop high blood pressure throughout middle age. But in older adults, women are more likely than men to develop high blood pressure.
• Lifestyle. Certain lifestyle habits can raise your risk for high blood pressure, such as eating too much sodium (salt) or not enough potassium, lack of exercise, drinking too much alcohol, and smoking.
• Family history and genetics. High blood pressure often runs in families. Many genes are linked to small increases in high blood pressure risk.
• Social and economic factors:
  • Research shows that factors such as income, education level, where you live, and the type of job you have may raise your risk of high blood pressure. For example, working early or late shifts can raise your risk.
  • Experiencing discrimination and poverty has been linked to high blood pressure. Also, some research has shown that trauma in childhood may raise the risk of high blood pressure.
• Certain medicines. Some medicines can raise your blood pressure, including:
  • Certain antidepressants
  • Decongestants (medicines to relieve a stuffy nose)
  • Hormonal birth control pills
  • Non-steroidal anti-inflammatory drugs (NSAIDs), which are a type of pain reliever
• Having certain other medical conditions, such as:
  • Some tumors
  • Chronic kidney disease
  • Diabetes
  • Metabolic syndrome
  • Overweight and obesity
  • Sleep apnea
  • Thyroid problems

You can help prevent high blood pressure by having a healthy lifestyle. This means:

• Eating a healthy diet. To help manage your blood pressure, you should limit the amount of sodium (salt) that you eat and increase the amount of potassium in your diet. It is also important to eat foods that are lower in fat, as well as plenty of fruits, vegetables, and whole grains. The DASH eating plan is an example of an eating plan that can help you to lower your blood pressure.
• Getting regular physical activity. Regular physical activity can help you maintain a healthy weight and lower your blood pressure.
• Being at a healthy weight. Being overweight or having obesity increases your risk for high blood pressure. Maintaining a healthy weight can help you control high blood pressure and reduce your risk for other health problems.
• Limiting alcohol. Drinking too much alcohol can raise your blood pressure. It also adds extra calories, which may cause weight gain.
• Not smoking. Cigarette smoking raises your blood pressure and puts you at higher risk for heart attack and stroke. If you do not smoke, don't start. If you do smoke, talk to yourprovider for help in finding the best way for you to quit.
• Managing stress. Learning how to relax and manage stress can improve your emotional and physical health and lower high blood pressure. Stress management techniques include exercising, listening to music, focusing on something calm or peaceful, and meditating.
• Getting enough high-quality sleep.

If you already have high blood pressure, it is important to prevent it from getting worse or causing complications. You need to get regular medical care and follow your treatment plan. Your plan will include healthy lifestyle habit recommendations and possibly medicines.

Intestinal Obstruction

An intestinal obstruction occurs when food or stool cannot move through the intestines. The obstruction can be complete or partial. There are many causes. The most common are adhesions, hernias, cancers, and certain medicines.

Symptoms include:

• Severe abdominal pain or cramping
• Vomiting
• Bloating
• Loud bowel sounds
• Swelling of the abdomen
• Inability to pass gas
• Constipation

A complete intestinal obstruction is a medical emergency. It often requires surgery.

Itching

What is itching?

Itching is an irritating sensation that makes you want to scratch your skin. Sometimes it can feel like pain, but it is different. Often, you feel itchy in one area in your body, but sometimes you may feel itching all over. Along with the itching, you may also have a rash or hives.

Itching is a symptom of many health conditions. Some common causes are:

• Allergic reactions to food, insect bites, pollen, and medicines
• Skin conditions such as eczema, psoriasis, and dry skin
• Irritating chemicals, cosmetics, and other substances
• Parasites such as pinworms, scabies, head and body lice
• Pregnancy
• Liver, kidney, or thyroid diseases
• Certain cancers or cancer treatments
• Diseases that can affect the nervous system, such as diabetes and shingles

Most itching is not serious. To feel better, you could try:

• Applying cold compresses
• Using moisturizing lotions
• Taking lukewarm or oatmeal baths
• Using over-the-counter hydrocortisone cream or antihistamines
• Avoiding scratching, wearing irritating fabrics, and exposure to high heat and humidity

Contact your health care provider if your itching is severe, does not go away after a few weeks, or does not have an apparent cause. You may need other treatments, such as medicines or light therapy. If you have an underlying disease that is causing the itching, treating that disease may help.

Jaundice

Jaundice causes your skin and the whites of your eyes to turn yellow. Too much bilirubin causes jaundice. Bilirubin is a yellow chemical in hemoglobin, the substance that carries oxygen in your red blood cells. As red blood cells break down, your body builds new cells to replace them. The old ones are processed by the liver. If the liver cannot handle the blood cells as they break down, bilirubin builds up in the body and your skin may look yellow.

Many healthy babies have some jaundice during the first week of life. It usually goes away. However, jaundice can happen at any age and may be a sign of a problem. Jaundice can happen for many reasons, such as:

• Blood diseases
• Genetic syndromes
• Liver diseases, such as hepatitis or cirrhosis
• Blockage of bile ducts
• Infections
• Medicines
