Diseases That Start With Z

Let’s discover the diseases that start with Z in our post today.

Diseases are a ubiquitous part of life and medical science. They are defined as any condition that impairs the normal functioning of the body or its organs, and can manifest in a variety of ways. From the common cold to cancer, diseases can range from mild to severe, acute to chronic, and infectious to non-infectious. The study of diseases is called pathology, and it involves understanding the causes, symptoms, diagnosis, and treatment of various ailments affecting humans and animals.

The process of creating a list of diseases that started with every alphabet required patience, an eye for detail, and an extensive knowledge of medical terms. I meticulously researched and reviewed each medical terminology to ensure that every disease was accurately categorized by the first letter of the name.

So, let’s begin exploring this list of diseases starting with Z!

15 Diseases That Start With Z

And here’s the list of diseases that begin with Z letter.

Zonular Cataract and Nystagmus

Zonular cataract is a type of cataract that develops due to the disintegration of zonular fibers found in the eye’s lens. This type of cataract can lead to blurred vision and sensitivity to light. Nystagmus is a type of eye movement disorder that causes the eyes to move involuntarily in various directions, making it challenging to focus on objects. In some cases, these conditions can occur together, causing significant vision issues.

Zika Virus

The Zika virus is a mosquito-borne disease that primarily affects tropical regions. Symptoms of this virus include fever, rash, joint pain, and conjunctivitis. Pregnant women are particularly at risk as the virus can cause microcephaly, a condition where the baby’s head is smaller than average. Furthermore, the virus can also cause Guillain-Barré Syndrome, a condition where the body’s immune system attacks the nervous system. Currently, there is no vaccine for the Zika virus, and the best way to prevent the disease is to protect oneself from mosquito bites.

Zinc Deficiency

Zinc is an essential nutrient required by the body for various functions, including DNA synthesis, cell growth, and immune system health. However, a zinc deficiency can lead to several health problems, including delayed wound healing, hair loss, and diarrhea. In children, a zinc deficiency can cause stunted growth and developmental delays. Zinc deficiency is common in areas where diets are low in zinc, such as developing countries.

Zika Fever

Zika fever or Zika virus disease is a viral illness transmitted by mosquitoes. The illness is similar to dengue fever, with symptoms such as fever, rash, joint pain, and headache. The illness typically lasts around four to seven days and is rarely fatal. However, as mentioned earlier, pregnant women are at risk of the virus causing microcephaly in their unborn child. So, it’s necessary to take precautions to prevent mosquito bites.


Zimmerman syndrome is a rare genetic disorder that affects the cartilage and bone’s development, leading to short stature and joint problems. Individuals with Zimmerman syndrome may also have hearing loss and vision problems.

Zlotogora Syndrome

Zlotogora syndrome is an inherited disorder characterized by abnormal physical features such as gap in hand bones, abnormal fingers, and folds in palms, and abnormalities in the hair, skin, and teeth. The syndrome is also linked with immune system problems, resulting in frequent infections.

Zellweger Syndrome

Zellweger syndrome is a severe, inherited disorder that affects the brain, liver, and kidneys. Infants with Zellweger syndrome typically have little to no muscle tone, difficulty breathing, seizures, and vision and hearing problems. There are currently no cures for Zellweger syndrome, and treatment primarily focuses on managing symptoms.

Zechi-Ceide Syndrome

Zechi-Ceide Syndrome is a rare inherited disorder characterized by intellectual disability, distinctive facial features, and skeletal abnormalities such as scoliosis and shortened bones in fingers and toes. The condition affects both sexes equally and is caused by a mutation in the CTNNB1 gene.

Zinc Toxicity

While zinc is an essential nutrient, too much of it can cause toxicity, leading to nausea, vomiting, diarrhea, and other symptoms. Zinc toxicity can also interfere with the absorption of other nutrients such as copper and iron. High doses of zinc supplements should be avoided.


Zygomycosis is a type of fungal infection that primarily affects individuals with weakened immune systems. The infection typically affects the lungs, sinuses, or skin, and symptoms vary depending on the site of infection. Treatment for Zygomycosis primarily involves antifungal medication, and in severe cases, surgery may be required.


Zunich syndrome is an inherited condition that affects the connective tissues in the body, leading to various physical abnormalities such as short stature, joint problems, and skin conditions. The severity of the condition can vary from person to person.

Zollinger-Ellison syndrome is a condition that causes excessive gastric acid production, leading to stomach ulcers and other digestive problems. The condition is caused by a tumor in the pancreas or duodenum and is treated primarily with medication and surgery.

Wrapping Up

And that’s our list of Z diseases.

As I started compiling the list of diseases that begins with every alphabet, I realized how vast and complex the world of medical conditions is. It required meticulous research, attention to detail and an extensive database of medical terminologies to come up with a comprehensive list that covered all possible diseases for each alphabet.

In conclusion, diseases have been a part of human history and their impact has been grave. From communicable diseases that can be easily spread to chronic ailments that affect individuals for a long time, diseases have taken a toll on the health and well-being of individuals and communities across the world.

Hope this post on diseases beginning with Z alphabet has been useful to you!
