Non-acquired panhypopituitarism

What it is

From: Orphanet

A rare genetic pituitary disease characterized by variable deficiency of all hormones produced in the anterior lobe of the pituitary gland. Clinical manifestations include hypothyroidism, hypogonadism, growth retardation and short stature, and secondary adrenal insufficiency. Age of onset is variable. Signs and symptoms usually develop gradually, and loss of the different hormones is often sequential.

Reported clinical features and what the terms mean

The following findings are associated with this condition in Orphanet. They are not a checklist for diagnosing yourself, and they do not all occur in every affected person. Some are examination, imaging or laboratory findings that cannot be recognised at home.

The frequency labels describe how often a finding was reported among people with the condition in the source. They do not give the chance that a person with that symptom has the condition. Definitions below reproduce HPO terminology; they explain the term, not the likely severity in an individual.

Hypopituitarism · Obligate (100%)

Abnormality of secondary sexual hair · Frequent (79-30%)

Abnormality of the growth of secondary sexual hair, which normally ensues during puberty. In males, secondary sexual hair usually comprises body hair, including underarm, abdominal, chest, and pubic hair. In females, secondary sexual hair usually comprises a lesser degree of body hair, most prominently underarm and pubic hair.

Amenorrhea · Frequent (79-30%)

Absence of menses for an interval of time equivalent to a total of more than (or equal to) 3 previous cycles or 6 months.

Anterior pituitary hypoplasia · Frequent (79-30%)

Underdevelopment of the anterior pituitary gland.

Aplasia/Hypoplasia of the breasts · Frequent (79-30%)

Absence or underdevelopment of the breasts.

Decreased circulating ACTH level · Frequent (79-30%)

The concentration of corticotropin, also known as adrenocorticotropic hormone (ACTH), is below the lower limit of normal in the blood circulation.

Decreased response to growth hormone stimulation test · Frequent (79-30%)

Insufficient responses to growth hormone (GH) provocation tests. GH deficiency is defined as a serum peak GH concentration less than 10 ng/mL on provocation with a combination of at least two separate stimulation tests.

Decreased testicular size · Frequent (79-30%)

Reduced volume of the testicle (the male gonad).

Depressed nasal ridge · Frequent (79-30%)

Lack of prominence of the nose resulting from a posteriorly-placed nasal ridge.

Fatigue · Frequent (79-30%)

A subjective feeling of tiredness characterized by a lack of energy and motivation.

Growth delay · Frequent (79-30%)

A deficiency or slowing down of growth pre- and postnatally.

Hypoglycemia · Frequent (79-30%)

A decreased concentration of glucose in the blood.

Hypogonadotropic hypogonadism · Frequent (79-30%)

Hypogonadotropic hypogonadism is characterized by reduced function of the gonads (testes in males or ovaries in females) and results from the absence of the gonadal stimulating pituitary hormones: follicle stimulating hormone (FSH) and luteinizing hormone (LH).

Hypotension · Frequent (79-30%)

Low Blood Pressure, vascular hypotension.

Which doctor should you see?

The suggested department for discussing Non-acquired panhypopituitarism is Endocrinology, with a endocrinologist as the relevant type of clinician. General physician / Family Medicine; paediatrician for children. Referral depends on symptoms.

Additional services that may be relevant, depending on the findings, include: Clinical Genetics.

This is an editorial referral starting point. The appropriate clinic depends on the person’s age, symptoms, previous diagnosis and local services. The first clinician can decide whether another specialty or a team is needed; a department label does not confirm the diagnosis.

How to prepare for an assessment

Bring a short timeline of the main symptoms: when they first appeared, whether they are constant or episodic, what seems to change them, and how they affect daily activities. Include previous reports, discharge summaries, current medicines and supplements, allergies, and any relevant family history. A dated record is more useful than trying to match every feature in an online article.

Ask the clinician what is already established and what remains uncertain. If a test is suggested, ask what question it answers, what its limitations are and how the result would change the next step. The information here is not an instruction to arrange every possible test. In children, bring growth, developmental and school information if it is relevant to the concern.

• Which hormone or metabolic finding is important in this case?
• How should test timing and current medicines be taken into account?
• What follow-up would show whether the care plan is working?

Treatment discussions and follow-up

The material gathered for this draft does not provide a complete condition-specific treatment pathway for Non-acquired panhypopituitarism. That gap does not mean that treatment is unavailable. A clinician needs to establish the diagnosis and review current guidance before recommending medicines, procedures, rehabilitation or other support.

Before leaving the appointment, clarify the next review date, who will communicate results, and whom to contact if the situation changes. Discuss difficulties with sleep, work, school, mobility, eating or emotional wellbeing when these are relevant. Practical support may require coordination between the treating clinician and other services.

The collected references do not establish a complete prevention or long-term outlook section for this entry. Missing information should not be interpreted as proof that prevention is impossible or that a particular outcome is inevitable. Ask what is known for the exact subtype, stage and personal circumstances, and which uncertainties remain.

When to seek emergency help

Severe breathing difficulty, collapse, new stroke-like symptoms, a seizure that is prolonged or repeated without recovery, uncontrolled major bleeding, or an immediate risk of self-harm require emergency help. In India, call 112 or reach the nearest emergency department. This is a general, non-exhaustive warning list; it is not a condition-specific triage tool.
