NIDDK Frequently Asked Questions
Some of the most common questions about the NIDDK are answered below.
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) is part of the National Institutes of Health (NIH), the nation’s medical research agency. We conduct and support biomedical research, disseminating research findings and health information to the public, and are part of the U.S. government under the Department of Health and Human Services.
NIDDK offices and labs are located on and near the NIH campus in Bethesda, MD. The NIDDK's Phoenix Epidemiology and Clinical Research Branch is located in Arizona. View our Visit Us page for our address and links to maps and information for visitors.
The NIDDK, like the rest of the NIH, receives federal funding from congressional appropriations. Each year, the NIDDK submits written testimony to the congressional appropriations subcommittee outlining current and future research plans.
The NIDDK does not diagnose or provide specific medical advice. A doctor who has examined you and knows your medical history is the best person to answer your medical questions.
The NIDDK offers general information on various health topics. To review available topics, visit our Health Information landing page. If we don’t cover the topic you are looking for, the NIH Health Information may be of use.
You can search the NIH's MedlinePlus for consumer-friendly information, including links to health topics, medical tests, videos, and more.
You can also search another NIH resource, PubMed, for scientific papers, journals, and online books. These articles are often written at an advanced scientific level. Your doctor or another trusted health care professional may be able to help you understand them.
For further assistance send your question to the NIDDK Health Information Center, or call us at 1-800-860-8747 between 8:30 a.m. and 5 p.m. Monday – Friday.
The NIDDK cannot provide referrals and does not rank physicians or hospitals. You may want to ask your doctor for a referral to a specialist or recommendation on the best place to go for treatment. You also can contact a local medical society or organization for a listing of specialists in your area.
The NIH Clinical Center is a research hospital that only accepts patients who are participating in a research study. To be considered for a study, patients must have a physician referral, a specific diagnosis, and meet other study requirements. To learn more about ongoing clinical trials and potentially participate in a study, view the NIH Clinical Center's Trials.
Practicing physicians who would like to consult with an NIDDK specialist should contact the NIDDK investigator directly.
For clinical standards and treatment guidelines, search the National Guideline Clearinghouse, a public resource for evidence-based clinical practice guidelines.
The National Center for Complementary and Integrative Health (NCCIH) is part of the NIH, and is a good source for this information.
We recommend asking your health care team or your local hospital for information about support groups.
Donating to NIDDK
The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), of the National Institutes of Health, is a Federal Government research agency funded by Congressional appropriations. However, NIDDK is also authorized by the U.S. Congress to accept donations and bequests to support its mission. We do not solicit funds or participate in fundraising activities. Gifts must be entirely voluntary.
A gift will be considered “conditional” if the donor restricts its purpose to support research on a specific disease or a specific research study, project, or conference; to support activities of an NIDDK employee identified by name or organizational title; for specifically identified functions, such as observances, ceremonies, particular public information or health promotion campaigns, community outreach activities; or purchase of a specific item or types of equipment, or other specific uses. A gift will be considered “unconditional” if it is made to or for the NIDDK for general purposes without further specification as to its purpose or manner of use. “Unconditional” donations will be merged into a general account to be used at the discretion of the NIDDK Director to support any type of research or activity related to NIDDK’s mission.
A contribution can be made to NIDDK by sending a check, money order, or wire transfer payable to "The National Institute of Diabetes and Digestive and Kidney Diseases" addressed to:
National Institutes of Health
National Institute of Diabetes and Digestive and Kidney Diseases
Office of Financial Management and Analysis
9000 Rockville Pike, MSC 2560
Building 31, Room 9A34
Bethesda, MD 20892
A letter should be sent along with the check or money order indicating the purpose of the donation. For wire transfer instructions, please contact the number below. If a contribution is to be made as a memorial, please indicate the name of the deceased as well as a name and address of the individual(s) to whom an acknowledgment can be sent. All donors are acknowledged.
If you are considering a bequest in a will, the will should show the address of the National Institute of Diabetes and Digestive and Kidney Diseases to avoid confusion about your intentions. The will should indicate that the bequest is to be used to support the research and related activities of the National Institute of Diabetes and Digestive and Kidney Diseases (unconditional) or a specific disease or research project/study (conditional). In the absence of the will specifying the NIDDK, bequests to benefit research related to diabetes, kidneys, endocrinology, digestive diseases, nutrition, or any of the named diseases within the NIDDK mission may also be accepted as a gift.
The decision whether to accept any gift is a discretionary administrative decision, based upon program needs and public policy considerations. Most gifts are accepted when they will be beneficial to NIDDK, as long as any conditions of the gift are not illegal, contrary to public policy, or burdensome and the gift will not create a real or apparent conflict of interest, as could occur when a gift is offered by an organization with which NIDDK has financial dealings.
NIDDK is a Federal Agency of the United States Government and is recognized by the Internal Revenue Service as tax-exempt under 26 U.S.C. 501(c)(3). Contributions to the NIDDK are tax-deductible pursuant to 26 U.S.C 170. Potential donors should, however, consult with their tax advisors.
