How a pancreas transplant can cure diabetes

Diabetes is a chronic condition that impairs the body's ability to regulate blood sugar due to inadequate insulin production. Producing insulin is a function of the pancreas — a long, flat gland that sits behind the stomach in the upper abdomen. People with diabetes can experience significant complications from the disease, including heart disease, chronic kidney disease, nerve damage and vision loss. While advances have been made in diabetes treatments, many people with diabetes struggle...


Regenerating damaged skin

Regenerative medicine is an emerging field that looks to repair, replace or restore diseased cells, tissues or organs. One specialty that's a natural fit for regenerative medicine is dermatology. That's because the skin is the largest organ that regenerates in the body. "Regenerative medicine is the idea that we can reestablish form and function," says Dr. Saranya Wyles, a Mayo Clinic dermatologist. "So when we are born, we have that baby skin. And as we age, that sort of shifts and changes...


The importance of HIV testing

The COVID-19 pandemic has led people to delay testing and treatments for a variety of diseases and conditions. This includes HIV testing. During the pandemic, the number HIV diagnosis decline, but that decline is most attributed to declines in testing, according to the Centers for Disease Control and Prevention. Experts attribute this decline to less frequent visits to health centers, reduced outreach services, and shifting of public health staff to COVID-19 response activities. June 27 is...


What to expect after breast cancer

After skin cancer, breast cancer is the most common cancer diagnosed in women in the U.S. But it can occur in people of all gender identities. Nearly 13% of women in the U.S. will be diagnosed with breast cancer at some point, according to the National Cancer Institute. Fortunately, thanks to earlier detection and advances in diagnosis and treatment, most people diagnosed with breast cancer will survive. Understanding what to expect can make the cancer journey smoother. "It's important for...


COVID-19 update

As immunity wanes for many vaccinated adults and omicron and its subvariants continue to circulate, it seems that just about everyone knows someone with a case of COVID-19. The steady increase in COVID-19 infections is due to changing, highly contagious variants, explains Dr. Gregory Poland, an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group. Dr. Poland says it’s still important to take the precaution of mask-wearing in public areas, even if you have been...


LGBTQ community face barriers to care

LGBTQ people can face specific health concerns related to their gender incongruence, sexual orientation, practices and social stigma. People in the LGBTQ community often experience barriers to accessing health care and preventive services, which can result in disparities in both cancer risk and treatment. "Many of those disparities are rooted in stigma and discrimination that have really historically been an issue for this population," says Dr. Jewel Kling, chair of the Women's Health...


Ear Tubes

An ear infection is an infection of the middle ear, the air-filled space behind the eardrum that contains the tiny vibrating bones of the ear. Children are more likely than adults to get ear infections. Because ear infections often clear up on their own, treatment may begin with managing pain and monitoring the problem. Sometimes, antibiotics are used to clear the infection. Some people are prone to having multiple ear infections. This can cause hearing problems and other serious...


Palliative care for people with cancer designed to fit the needs of each patient

Palliative care is offered alongside cancer treatment to help people with cancer manage symptoms and improve the quality of life for them and their families. Palliative care is specialized medical care that focuses on relieving patients' pain and other symptoms of serious illness no matter the diagnosis or stage of disease. "The palliative care team really focuses on addressing symptoms and needs so that we can help people feel as comfortable as they can as they go through their treatment...


Getting kids involved in the kitchen

If your child is a picky eater, the battle over healthy foods can be a challenge. Being fussy about food is common in toddlers and small children, but parents can try some tips and tricks to introduce new foods. One approach to improving eating habits is to get kids involved in the kitchen. Involving children in meal planning and teaching kids to cook can have multiple benefits. Not only is cooking a necessary life skill, learning how to cook teaches math, science and creativity. Using...


Ask the Mayo Mom: Surgical options to repair pectus excavatum

Pectus excavatum is a condition where a person's breastbone is sunken into the chest. While the sunken breastbone is often noticeable shortly after birth, the severity of pectus excavatum typically worsens during the adolescent growth spurt. "The initial diagnosis is often based on appearance," explains Dr. Denise Klinkner, a pediatric surgeon at Mayo Clinic Children’s Center and practice chair of the Division of Pediatric Surgery at Mayo Clinic. "Then when we try to grade the severity,...


Community leaders are key to reaching people underrepresented in research

To address health disparities and reach underserved communities, work is underway at Mayo Clinic to raise up community voices through community engagement. "Community engagement is an ongoing process," explains Dr. Chyke Doubeni, director of Mayo Clinic’s Center for Health Equity and Community Engagement Research. "It's a partnership or collaboration among organizational entities and members of the community. And the sole purpose of this is to solve problems and address priorities that a...


Don't ignore the warning signs of stroke

On average, someone in the U.S. has a stroke every 40 seconds, according to the Centers for Disease Control and Prevention. A stroke is a medical emergency, and prompt treatment is crucial. Early action can reduce brain damage and other complications. A stroke occurs when the blood supply to part of the brain is interrupted, depriving the brain of oxygen. It's important to recognize the warning signs of stroke, because prompt treatment can minimize brain damage. Every moment is...


Consider all treatment options for ovarian cancer, including clinical trials

Ovarian cancer is the fifth-leading cause of cancer death among women in the U.S. When ovarian cancer first develops, it might not cause noticeable symptoms. It often goes undetected until it has spread within the pelvis and abdomen. "Unfortunately, ovarian cancer often presents with very common symptoms, and these common symptoms are things that everybody will complain about at some point," explains Dr. John Weroha, a Mayo Clinic medical oncologist. "For example, constipation, bloating,...


COVID-19 update

The widespread availability of at-home COVID-19 tests have made it easier for people to know if they have the virus, and to take measures to protect themselves and others. But there is a downside. Because the majority of tests are now done at home and often not reported, the official counts on COVID-19 infection rates are not as accurate as they have been in past waves of the virus. "Because the majority of testing is being done at home, we can no longer tell you accurately about the...


Ask the Mayo Mom: Polycystic kidney disease can affect children, too

Polycystic kidney disease is an inherited disorder where clusters of cysts develop within the kidneys, causing the kidneys to enlarge and lose function over time. The cysts, which are noncancerous sacs containing fluid, vary in size, and they can grow to be large. This disorder can occur in children and adults. The two main types of polycystic kidney disease, caused by different genetic flaws, are: Autosomal dominant polycystic kidney disease (ADPKD).Autosomal recessive polycystic kidney...


Mohs surgery for melanoma

Melanoma is the most serious type of skin cancer. It develops in the cells that produce melanin, the pigment that gives skin its color. Melanoma is one of the most common cancer types in the U. S. Roughly 2% of people will be diagnosed with melanoma of the skin at some point during their lifetime, according to the National Cancer Institute. Treatment for early stage melanomas usually includes surgery to remove the melanoma. Mohs surgery is a precise surgical technique used to treat skin...


National Nurses Week

At Mayo Clinic, the Department of Nursing consists of over 22,000 people, including nurses, patient care assistants, patient care technicians and social workers. Like many health care professionals, the COVID-19 pandemic has been a stressful and challenging time for those in the department. "Throughout the pandemic, our nurses have continued to be there for their patients," says Ryannon Frederick, Mayo Clinic's chief nursing officer. "Our patient satisfaction actually increased during the...


What parents should know about the new hepatitis outbreak in children

At least 16 countries and 10 U.S. states have identified unusual hepatitis cases in children. Experts advise that cases are extremely rare, with about 200 children affected worldwide. Hepatitis is inflammation of the liver. It is most commonly caused by a viral infection, although there are other potential causes. A common adenovirus is being investigated as a potential cause for this hepatitis outbreak. Adenoviruses are a group of viruses that typically cause respiratory and GI tract...


Ask the Mayo Mom: How and why endoscopy is used in children

Endoscopy is a nonsurgical procedure used to visually examine the digestive system with a tiny camera on the end of a long, flexible tube. An upper endoscopy examines the stomach, esophagus and small intestines. A colonoscopy, which is another type of endoscopy, is used to examine the rectum, large intestine and colon. In children, endoscopy can be used to look for causes of unexplained abdominal pain, to diagnose swallowing disorders or to identify conditions including Crohn's disease,...


COVID-19 news update

An estimated 3 out of 4 U.S. children and more than half of all adults have been infected with COVID-19, according to a report released on Tuesday, April 26 by the Centers for Disease Control and Prevention. But a Mayo Clinic expert says more information is needed to get the complete picture. "This was a convenient sample. In other words, people who were having blood drawn for other reasons were tested,"explains Dr. Gregory Poland, head of Mayo Clinic's Vaccine Research Group. "That does...
