Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells.
Stem cells are different from other cells in the body in three ways:
- They can divide and renew themselves over a long time
- They are unspecialized, so they cannot do specific functions in the body
- They have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells
Doctors and scientists are excited about stem cells because they could help in many different areas of health and medical research. Studying stem cells may help explain how serious conditions such as birth defects and cancer come about. Stem cells may one day be used to make cells and tissues for therapy of many diseases. Examples include Parkinson's disease, Alzheimer's disease, spinal cord injury, heart disease, diabetes, and arthritis.

What is telehealth?
Telehealth is the use of communications technologies to provide health care from a distance. These technologies may include computers, cameras, videoconferencing, the Internet, and satellite and wireless communications. Some examples of telehealth include:
- A "virtual visit" with a health care provider, through a phone call or video chat
- Remote patient monitoring, which lets your provider check on you while you are at home. For example, you might wear a device that measures your heart rate and sends that information to your provider.
- A surgeon using robotic technology to do surgery from a different location
- Sensors that can alert caregivers if a person with dementia leaves the house
- Sending your provider a message through your electronic health record (EHR)
- Watching an online video that your provider sent you about how to use an inhaler
- Getting an email, phone, or text reminder that it's time for a cancer screening
What is the difference between telemedicine and telehealth?
Sometimes people use the term telemedicine to mean the same thing as telehealth. Telehealth is a broader term. It includes telemedicine. But it also includes things like training for health care providers, health care administrative meetings, and services provided by pharmacists and social workers.
What are the benefits of telehealth?
Some of the benefits of telehealth include:
- Getting care at home, especially for people who can't easily get to their providers' offices
- Getting care from a specialist who is not close by
- Getting care after office hours
- More communication with your providers
- Better communication and coordination between health care providers
- More support for people who are managing their health conditions, especially chronic conditions such as diabetes
- Lower cost, since virtual visits may be cheaper than in-person visits
What are the problems with telehealth?
Some of the problems with telehealth include:
- If your virtual visit is with someone who is not your regular provider, he or she may not have all of your medical history
- After a virtual visit, it may be up to you to coordinate your care with your regular provider
- In some cases, the provider may not be able to make the right diagnosis without examining you in person. Or your provider may need you to come in for a lab test.
- There may be problems with the technology, for example, if you lose the connection, there is a problem with the software, etc.
- Some insurance companies may not cover telehealth visits
What types of care can I get using telehealth?
The types of care that you can get using telehealth may include:
- General health care, like wellness visits
- Prescriptions for medicine
- Dermatology (skin care)
- Eye exams
- Nutrition counseling
- Mental health counseling
- Urgent care conditions, such as sinusitis, urinary tract infections, common rashes, etc.
For telehealth visits, just like with an in-person visit, it is important to be prepared and have good communication with the provider.
What is urinary incontinence (UI)?
Urinary incontinence (UI) is the loss of bladder control, or being unable to control urination. It is a common condition. It can range from being a minor problem to something that greatly affects your daily life. In any case, it can get better with proper treatment.
What are the types of urinary incontinence (UI)?
There are several different types of UI. Each type has different symptoms and causes:
- Stress incontinence happens when stress or pressure on your bladder causes you to leak urine. This could be due to coughing, sneezing, laughing, lifting something heavy, or physical activity. Causes include weak pelvic floor muscles and the bladder being out of its normal position.
- Urge, or urgency, incontinence happens when you have a strong urge (need) to urinate, and some urine leaks out before you can make it to the toilet. It is often related to an overactive bladder. Urge incontinence is most common in older people. It can sometimes be a sign of a urinary tract infection (UTI). It can also happen in some neurological conditions, such as multiple sclerosis and spinal cord injuries.
- Overflow incontinence happens when your bladder doesn't empty all the way. This causes too much urine to stay in your bladder. Your bladder gets too full, and you leak urine. This form of UI is most common in men. Some of the causes include tumors, kidney stones, diabetes, and certain medicines.
- Functional incontinence happens when a physical or mental disability, trouble speaking, or some other problem keeps you from getting to the toilet in time. For example, someone with arthritis may have trouble unbuttoning his or her pants, or a person with Alzheimer's disease may not realize they need to plan to use the toilet.
- Mixed incontinence means that you have more than one type of incontinence. It's usually a combination of stress and urge incontinence.
- Transient incontinence is urine leakage that is caused by a temporary (transient) situation such as an infection or new medicine. Once the cause is removed, the incontinence goes away.
- Bedwetting refers to urine leakage during sleep. This is most common in children, but adults can also have it.
- Bedwetting is normal for many children. It is more common in boys. Bedwetting is often not considered a health problem, especially when it runs in the family. But if it still happens often at age 5 and older, it may be because of a bladder control problem. This problem could be caused by slow physical development, an illness, making too much urine at night, or another problem. Sometimes there is more than one cause.
- In adults, the causes include some medicines, caffeine, and alcohol. It can also be caused by certain health problems, such as diabetes insipidus, a urinary tract infection (UTI), kidney stones, enlarged prostate (BPH), and sleep apnea.
Who is at risk for urinary incontinence (UI)?
In adults, you are at higher risk of developing UI if you:
- Are female, especially after going through pregnancy, childbirth, and/or menopause
- Are older. As you age, your urinary tract muscles weaken, making it harder to hold in urine.
- Are a man with prostate problems
- Have certain health problems, such as diabetes, obesity, or long-lasting constipation
- Are a smoker
- Have a birth defect that affects the structure of your urinary tract
In children, bedwetting is more common in younger children, boys, and those whose parents wet the bed when they were children.
How is urinary incontinence (UI) diagnosed?
Your health care provider may use many tools to make a diagnosis:
- A medical history, which includes asking about your symptoms. Your provider may ask you to keep a bladder diary for a few days before your appointment. The bladder diary includes how much and when you drink liquids, when and how much you urinate, and whether you leak urine.
- A physical exam, which can include a rectal exam. Women may also get a pelvic exam.
- Urine and/or blood tests
- Bladder function tests
- Imaging tests
What are the treatments for urinary incontinence (UI)?
Treatment depends on the type and cause of your UI. You may need a combination of treatments. Your provider may first suggest self-care treatments, including:
- Lifestyle changes to reduce leaks:
- Drinking the right amount of liquid at the right time
- Being physically active
- Staying at a healthy weigh
- Avoiding constipation
- Not smoking
- Bladder training. This involves urinating according to a schedule. Your provider makes a schedule from you, based on information from your bladder diary. After you adjust to the schedule, you gradually wait a little longer between trips to the bathroom. This can help stretch your bladder so it can hold more urine.
- Doing exercises to strengthen your pelvic floor muscles. Strong pelvic floor muscles hold in urine better than weak muscles. The strengthening exercises are called Kegel exercises. They involve tightening and relaxing the muscles that control urine flow.
If these treatments do not work, your provider may suggest other options such as:
- Medicines, which can be used to
- Relax the bladder muscles, to help prevent bladder spasms
- Block nerve signals that cause urinary frequency and urgency
- In men, shrink the prostate and improve urine flow
- Medical devices, including
- A catheter, which is a tube to carry urine out of the body. You might use one a few times a day or all the time.
- For women, a ring or a tampon-like device inserted into the vagina. The devices pushes up against your urethra to help decrease leaks.
- Bulking agents, which are injected into the bladder neck and urethra tissues to thicken them. This helps close your bladder opening so you have less leaking.
- Electrical nerve stimulation, which involves changing your bladder's reflexes using pulses of electricity
- Surgery to support the bladder in its normal position. This may be done with a sling that is attached to the pubic bone.
