What kind of doctor treats Apoplexy?
Pituitary apoplexy is usually treated by an endocrinologist, a hormone doctor, often with a neurosurgeon, a doctor who operates on the brain. Sudden stroke-like symptoms always need emergency care first. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is apoplexy?
Apoplexy means bleeding into an organ. It can also mean loss of blood flow to an organ. It is used for several conditions. One is pituitary apoplexy. That is bleeding into the pituitary gland. Apoplexy most often refers to stroke symptoms that occur suddenly. These symptoms can come from bleeding into the brain. They can also come from a blood clot in a brain blood vessel. Conditions such as subarachnoid hemorrhage, which is bleeding around the brain, or stroke are sometimes called apoplexy.
Apoplexy is named for the organ that is affected. For example, adrenal apoplexy means bleeding into the adrenal glands.
Symptoms
The symptoms below are for pituitary apoplexy. They usually start over a short time. They can be life threatening. Symptoms often include:
- Severe headache, often described as the worst of your life.
- Paralysis of the eye muscles. This causes double vision or problems opening an eyelid.
- Loss of side vision. Some people lose all vision in one or both eyes.
- Low blood pressure, nausea, loss of appetite, and vomiting.
- Personality changes.
Causes and who gets it
Pituitary apoplexy can come from bleeding into the gland. It can also come from blocked blood flow to the gland. The pituitary is a small gland at the base of the brain. It makes many hormones that control how the body works. A common cause is bleeding inside a noncancerous tumor of the gland. These tumors are very common and often not diagnosed. The gland gets damaged when the tumor suddenly grows. A larger tumor means a higher risk. In women who are not pregnant and do not have a pituitary tumor, other risk factors exist. These include bleeding disorders, diabetes, head injury, and radiation to the gland. In these situations, apoplexy is very rare.
How doctors diagnose it
A doctor performs a physical exam and asks about symptoms. Tests may include eye exams. An MRI or CT scan takes pictures of the inside of the body. Blood tests check hormone levels. These include ACTH, cortisol, and thyroid-stimulating hormone. If missing hormones are not replaced, other hormone problems can develop over time.
Treatment
Acute apoplexy may need surgery. Surgery relieves pressure on the gland and improves vision symptoms. Severe cases need emergency surgery. If vision is not affected, surgery is often not needed. Treatment with adrenal replacement hormones may be needed right away. These hormones are called glucocorticoids. They are often given through the vein. Other hormones may be replaced later. These include growth hormone, sex hormones, thyroid hormone, and vasopressin.
When to see a doctor
Call 911 if you have a sudden, severe headache, sudden weakness, trouble speaking, or sudden dizziness. These can be signs of a stroke. Also call for eye muscle weakness, vision loss, or low blood pressure with fainting, nausea, or vomiting. These are symptoms of acute pituitary apoplexy. It can be life threatening. If you have a pituitary tumor and get these symptoms, seek medical help right away.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. After emergency treatment, some people need long-term hormone replacement. A primary care doctor can help manage follow-up visits. They can also coordinate your endocrinologist over time.
Common questions
Is apoplexy the same as a stroke?
Not exactly. Apoplexy most often means stroke symptoms that come on suddenly. So the words overlap. But it can also mean bleeding into other organs. These include the pituitary and adrenal glands. A subarachnoid hemorrhage or a stroke is sometimes called apoplexy.
Can pituitary apoplexy be treated?
Yes. Acute cases may need surgery. The surgery relieves pressure on the gland and improves vision. Severe cases need emergency surgery. If vision is not affected, surgery is often not needed. Treatment with adrenal replacement hormones may be needed right away.
What is the pituitary gland?
It is a small gland at the base of the brain. It makes many hormones that control essential body processes. If it is damaged, hormones may need to be replaced with medicines.
What is Sheehan syndrome?
It is pituitary bleeding in a woman during or right after childbirth. It is very rare. The first symptom may be a failure to produce milk after having a baby.
