In medical terms, “HD” most commonly stands for Hemodialysis, a treatment that filters waste, excess fluids, and toxins from the blood when the kidneys are not functioning properly. However, HD can also have several other medical meanings depending on context.
Medical abbreviations can be confusing, especially when the same letters stand for different conditions, treatments, or measurements. One abbreviation that often raises questions is “HD.” You may see it on medical reports, prescriptions, hospital charts, or lab results and wonder what it actually means.
In most healthcare settings, HD refers to hemodialysis, a life-saving treatment for people with kidney failure. But that’s not the only meaning. Depending on the medical specialty such as neurology, cardiology, or genetics HD can represent different terms, each with a very specific purpose.
In this guide, we’ll clearly explain what HD means in medical terms, explore its most common definitions, show real-world examples, compare related abbreviations, and help you understand how doctors use it in practice.
Primary Meaning of HD in Medical Terms: Hemodialysis
What Is Hemodialysis?
Hemodialysis (HD) is a medical treatment that cleans the blood when the kidneys are unable to do so.
- Blood is removed from the body
- Filtered through a dialysis machine
- Returned clean and balanced
Why Hemodialysis Is Needed
Hemodialysis is typically used for patients with:
- Chronic kidney disease (CKD)
- End-stage renal disease (ESRD)
- Acute kidney failure (in some cases)
Example Sentences
- “The patient has been on HD for three years.”
- “HD is scheduled three times a week.”
Tone: Clinical, neutral, professional
How HD (Hemodialysis) Is Used in Medical Records
In hospitals and clinics, HD is used as a shorthand to save time and space.
Common Medical Chart Examples
- HD x3/week – Hemodialysis three times per week
- On HD – Patient is currently receiving dialysis
- HD patient – Patient undergoing hemodialysis
💡 Tip: If you see “HD” alongside kidney-related terms, it almost always means hemodialysis.
