E-Cigarettes

E-cigarettes, or electronic cigarettes, are battery-operated smoking devices. They often look like cigarettes, but work differently. Using an e-cigarette is called vaping. The user puffs on the mouthpiece of a cartridge. This causes a vaporizer to heat the liquid inside the cartridge. The liquid contains nicotine, flavorings, and other chemicals. The heated liquid turns into the vapor that is inhaled.

Some people think that e-cigarettes are safer than cigarettes, and that they can be used to help people quit smoking. But not much is known about the health risks of using them, or whether they do help people quit smoking. However we do know about some dangers of e-cigarettes:

• They contain nicotine, which is addictive
• They contain other potentially harmful chemicals
• There is a link between e-cigarette use and tobacco cigarette use in teens
• The liquid in e-cigarettes can cause nicotine poisoning if someone drinks, sniffs, or touches it

Endocrine Diseases

Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include:

• Growth and development
• Metabolism - digestion, elimination, breathing, blood circulation and maintaining body temperature
• Sexual function
• Reproduction
• Mood

If your hormone levels are too high or too low, you may have a hormone disorder. Hormone diseases also occur if your body does not respond to hormones the way it is supposed to. Stress, infection and changes in your blood's fluid and electrolyte balance can also influence hormone levels.

In the United States, the most common endocrine disease is diabetes. There are many others. They are usually treated by controlling how much hormone your body makes. Hormone supplements can help if the problem is too little of a hormone.

Endometriosis

What is endometriosis?

The uterus, or womb, is the place where a fetus grows during pregnancy. The uterus is lined with tissue (endometrium). Endometriosis is a disease in which tissue like the lining of the uterus grows in other places in your body. These patches of tissue are called "implants," "nodules," or "lesions." They are most often found:

• On or under the ovaries
• On the fallopian tubes, which carry eggs from the ovaries to the uterus
• Behind the uterus
• On the tissues that hold the uterus in place
• On the bowels or bladder

In rare cases, the tissue may grow on your lungs or in other parts of your body.

Researchers don't know what causes endometriosis.

Endometriosis can affect anyone who menstruates. Certain factors can raise or lower your risk of getting it.

You are at higher risk if:

• You have a mother, sister, or daughter with endometriosis
• Your period started before age 11
• Your monthly cycles are short (less than 27 days)
• Your menstrual cycles are heavy and last more than 7 days

You have a lower risk if:

• You have been pregnant before
• Your periods started late in adolescence
• You breastfeed your babies

The main symptoms of endometriosis are:

• Pelvic pain, which often happens during your period
• Infertility

Other possible symptoms include:

• Painful menstrual cramps, which may get worse over time
• Pain during or after sex
• Pain in the intestine or lower abdomen
• Pain with bowel movements (pooping) or urination (peeing), usually during your period
• Heavy periods
• Spotting or bleeding between periods
• Digestive or gastrointestinal symptoms
• Fatigue or lack of energy

Surgery is the only way to know for sure that you have endometriosis. First, however, your health care provider will ask about your symptoms and medical history. You will have a pelvic exam and may have some imaging tests.

The most common surgery to diagnose endometriosis is a laparoscopy. This is a type of surgery that uses a laparoscope, a thin tube with a camera and light. The surgeon inserts the laparoscope through a small cut in the skin near your belly button. Your provider can make a diagnosis based on how the patches of endometriosis look. They may also do a biopsy to get a tissue sample.

There is no cure for endometriosis, but there are treatments for the symptoms. Your provider will work with you to decide which treatments would be best for you.

Treatments for endometriosis pain include:

• Pain relievers, including nonsteroidal anti-inflammatory drugs (NSAIDS) such as ibuprofen and a prescription medicine specifically for endometriosis. Providers may sometimes prescribe opioids for severe pain.
• Hormone therapy, which stops the ovaries from making hormones. This may slow the growth of the endometrial tissue and may stop new areas from growing. Types of hormone therapy include:
  • Birth control pills.
  • Progestin therapy.
  • Gonadotropin-releasing hormone (GnRH) medicines (GnRH agonists and antagonists). These medicines cause a temporary menopause. After your stop taking the medicines, your menstrual periods will start again, and pregnancy is possible.
• Surgical treatments for severe pain, including procedures to remove the endometriosis patches or cut some nerves in the pelvis. The surgery may be a laparoscopy or major surgery.

Treatments for infertility caused by endometriosis include:

• Laparoscopy to remove the endometriosis patches
• In vitro fertilization

Endoscopy

Endoscopy is a procedure that lets your doctor look inside your body. It uses an instrument called an endoscope, or scope for short. Scopes have a tiny camera attached to a long, thin tube. The doctor moves it through a body passageway or opening to see inside an organ. Sometimes scopes are used for surgery, such as for removing polyps from the colon.

There are many different kinds of endoscopy. Here are the names of some of them and where they look.:

• Arthroscopy: joints
• Bronchoscopy: lungs
• Colonoscopy and sigmoidoscopy: large intestine
• Cystoscopy and ureteroscopy: urinary system
• Laparoscopy: abdomen or pelvis
• Upper gastrointestinal endoscopy: esophagus and stomach

Exercise and Physical Fitness

What are the basics of exercise and physical fitness?

Exercise is anything that gets your body moving. Regular exercise is one of the best things you can do for your health. It has many benefits, including improving your overall health and fitness, and reducing your risk for many chronic (long-term) diseases.

Every physical fitness routine is built on a few simple ideas. These include:

• Make exercise a habit, as your body adapts to the type of activity you do most often. Regular practice will help you improve.
• Build up your activity level slowly to help you continue to get stronger, faster, or more flexible without pushing too hard all at once.
• Challenge yourself by lifting slightly heavier weights, adding a few more minutes to your walk, or increasing your pace.
• Mix up your workouts to keep things interesting and help prevent injuries or burnout.
• Show up regularly, even for short sessions, to help you continue to make progress.

There are many different types of exercise. Before you start, check with your health care provider, especially if you have trouble moving, balancing, or worry that exercise might not be safe for you.

A few main types of exercise include:

• Aerobic exercises such as walking, running, or swimming are sometimes referred to as cardio. This is short for cardiovascular exercise. These exercises increase your breathing and heart rate. They keep your heart, lungs, and circulatory system healthy and improve your overall fitness.
• Strength, or resistance training, exercises use weights, resistance bands, or your own body weight to build stronger muscles.
• Balance exercises, such as tai chi or standing on one leg, improve your stability and coordination. They may make it easier for you to walk on uneven surfaces and help prevent falls.
• Flexibility exercises, such as stretching or yoga, help your joints move more easily and improve your posture.

Most people benefit from a combination of these types of exercises. Your provider can help you choose the best type or amount of activity for you based on your fitness level and health.

Fitting regular exercise into your daily schedule may seem difficult at first. But you can start slowly and break your exercise time into chunks. Even small amounts of exercise can be helpful. You can work your way up to doing the recommended amount of exercise.How much exercise you needdepends on your age and health.

To get started, you don't need fancy equipment, but having the right tools can make it easier and more fun. There are a variety of places where you can exercise and create a routine that fits your lifestyle. This includes:

• At home. Dumbbells, kettlebells, a mat, or resistance bands are versatile and affordable options for strength training and stretching. A treadmill, a stationary bike, or a workout video are a few options for indoor cardio.
• A fitness center, gym, or health club. These places offer equipment, classes, and sometimes personal trainers for guidance and support. Ask if you can try the center before you join, and if staff are available to show you how to use the exercise equipment.
• Outdoors. Try riding a bike, walking your dog, or exploring local parks and trails. Dress for the weather and protect yourself from the sun. If safety is a concern, choose a well-lit neighborhood, a busy park, or even an indoor shopping mall for your walk.

Include activities that strengthen all parts of your body, especially your core, which are the muscles in your abdomen (belly), back, and hips. A strong core helps with balanceand stability and can lower your risk ofback injuries.

If youhaven't exercised in a while, start slowly and talk to your provider if you have health concerns. If you don't feel right, or have any pain, extremeshortness of breath, ordizziness, stop exercising and seek help right away.

Even with the best intentions, it's easy to fall off track. Here are some ways to keep going:

• Choose activities you enjoy. It's easier to make exercise a regular part of your life if you have fun doing it.
• Exercise safely. Use the proper equipment to preventinjuries, listen to your body, and don't overdo it.
• Give yourself goals. Your goals should be challenging, but realistic. It may be helpful to reward yourself when you reach them. The rewards could be something big, like new workout gear, or something smaller, such as a new water bottle or movie tickets.
• Mix it up. Try a new class, playlist, Podcast, or outdoor route when things get stale.
• Find an accountability partner. Exercise with a friend, join a group challenge, or check in with an online community.
• Use wearable technology. A pedometer or an app like a fitness tracker on your phone or other device can help you track your progress.
