Cushing’s syndrome is a condition that occurs when the body is exposed to too much cortisol, a hormone that helps regulate blood sugar, blood pressure, metabolism, and the body’s response to stress. In many cases, the condition develops because steroid medicines have been used for a long time or at high doses. Less commonly, it can be caused by tumours affecting hormone production.
Cushing’s syndrome can affect appearance, energy levels, blood pressure, and overall health. The condition often develops gradually, making it easy to mistake the symptoms for weight gain or normal ageing. Early diagnosis and treatment are important because untreated Cushing’s syndrome can increase the risk of diabetes, heart disease, infections, and other complications.
If you have noticed unusual weight gain around your abdomen, a rounded face, thinning skin, or other symptoms discussed below, speaking to a healthcare provider can help you understand the cause. Through Hope Plus, you can connect with a licensed healthcare provider in minutes for guidance, assessment, and advice on whether further testing or treatment may be needed.
Key Takeaways
- Cushing’s syndrome happens when the body has too much cortisol for a long period.
- Long-term use of steroid medicines is the most common cause.
- Symptoms include weight gain around the abdomen, a rounded face, thinning skin, and high blood pressure.
- Treatment depends on the underlying cause and often involves carefully reducing steroid medicines under medical supervision.
- Steroid medicines should never be stopped suddenly without professional advice.
What Is Cushing’s Syndrome?
Cortisol is a hormone produced by the adrenal glands. It plays an important role in many body functions, including controlling blood sugar, maintaining blood pressure, and helping the body respond to stress.
When cortisol levels remain too high for a long time, a collection of symptoms known as Cushing’s syndrome develops.
The condition may be caused by the body’s own overproduction of cortisol or by taking steroid medicines such as prednisolone or dexamethasone for prolonged periods.
Causes of Cushing’s Syndrome in Uganda
Long-Term Steroid Treatment
The most common cause of Cushing’s syndrome is the prolonged use of steroid medicines.
Examples include:
- Prednisolone
- Dexamethasone
- Hydrocortisone
- Other corticosteroid medicines
These medicines are used to treat many conditions, including asthma, severe allergies, autoimmune diseases, and some skin conditions. However, long-term use can lead to excessive cortisol levels.
Cushing’s Disease
Cushing’s disease is a specific condition in which a tumour in the pituitary gland causes excessive production of hormones that stimulate the adrenal glands to produce cortisol.
Adrenal Gland Tumours
Tumours affecting the adrenal glands can sometimes produce excess cortisol.
Examples include:
- Adrenal adenoma
- Adrenal carcinoma
Although these causes are less common, they require specialist assessment and treatment.
Symptoms of Cushing’s Syndrome
Symptoms usually develop slowly over months or years.
Changes in Body Shape
Many people notice:
- Weight gain around the abdomen and chest
- Relatively thinner arms and legs
- A rounded, puffy face often called a “moon face”
- Fat accumulation at the back of the neck and upper back, sometimes called a “buffalo hump”
Skin Changes
Excess cortisol affects the skin and connective tissues.
Symptoms may include:
- Thin, fragile skin
- Stretch marks (striae), especially on the abdomen
- Easy bruising
- Slow wound healing
Muscle and Physical Changes
People may experience:
- Muscle weakness
- Reduced muscle strength
- Muscle wasting or shrinking
- Difficulty climbing stairs or lifting objects
Symptoms in Women
Women may develop:
- Increased facial or body hair growth (hirsutism)
- Acne
- Menstrual irregularities
Effects on Blood Pressure and Blood Sugar
Cushing’s syndrome may cause:
- High blood pressure
- Elevated blood sugar levels
- Diabetes in some cases
When Should You See a Healthcare Provider?
Seek medical advice if you develop:
- Rapid or unexplained weight gain
- A rounded face together with abdominal weight gain
- Thin skin and easy bruising
- Muscle weakness
- Persistent high blood pressure
- High blood sugar levels
Early assessment can help identify the cause and prevent complications.
How Is Cushing’s Syndrome Diagnosed?
Medical and Drug History
A healthcare provider will ask about:
- Current medications
- Previous steroid use
- Duration of treatment
- Existing medical conditions
This step is especially important because steroid medicines are the most common cause.
Hormone Testing
If there is no clear history of steroid overuse, referral to a higher-level health facility may be necessary.
Specialised hormonal tests may be performed, including:
- Dexamethasone suppression testing
- Other hormone assessments as recommended by specialists
Conditions That May Resemble Cushing’s Syndrome
Some conditions can cause similar symptoms.
These include:
Ordinary Obesity
Weight gain alone does not necessarily mean a person has Cushing’s syndrome.
Alcohol-Related Pseudo-Cushing’s Syndrome
Heavy alcohol use can sometimes produce symptoms that resemble Cushing’s syndrome.
Healthcare providers use medical history, examination, and specialised tests to distinguish between these conditions.
Treatment of Cushing’s Syndrome
Treatment depends on the underlying cause.
If Steroid Medicines Are the Cause
This is known as iatrogenic Cushing’s syndrome.
Healthcare providers may gradually reduce the steroid dose over time.
The reduction is done slowly because stopping steroids suddenly can cause serious complications, including adrenal insufficiency.
The exact reduction schedule depends on:
- The type of steroid used
- The dose being taken
- How long treatment has continued
- The underlying condition being treated
Why Steroids Must Not Be Stopped Suddenly
Long-term steroid treatment can suppress the body’s natural hormone production.
Suddenly stopping treatment may leave the body unable to produce enough cortisol, resulting in adrenal insufficiency, which can become life-threatening.
Treatment for Non-Drug Causes
When Cushing’s syndrome is caused by a tumour or another medical condition, referral to a specialist is usually required.
Healthcare providers may arrange:
- Further hormone testing
- Imaging scans
- Specialist endocrine care
- Surgery or other treatments where appropriate
Possible Complications
Without treatment, Cushing’s syndrome may lead to:
- Diabetes
- High blood pressure
- Increased risk of infections
- Bone weakness
- Muscle wasting
- Delayed wound healing
- Reduced quality of life
Early treatment can significantly reduce these risks.
Prevention
Use Steroid Medicines Only as Prescribed
Steroids should only be used under the supervision of a qualified healthcare provider.
Avoid Self-Medication
Using steroid medicines without medical guidance increases the risk of serious side effects, including Cushing’s syndrome.
Attend Follow-Up Appointments
People receiving long-term steroid treatment should attend regular medical reviews to monitor for side effects and adjust treatment when necessary.
Never Stop Steroids Abruptly
Always follow a healthcare provider’s instructions when reducing or stopping steroid treatment.
Frequently Asked Questions
1. What is the most common cause of Cushing’s syndrome?
The most common cause is long-term use of steroid medicines such as prednisolone or dexamethasone.
2. Is Cushing’s syndrome the same as obesity?
No. Although weight gain is common, Cushing’s syndrome also causes other symptoms such as a moon face, thinning skin, muscle weakness, and high blood pressure.
3. Can steroid creams cause Cushing’s syndrome?
In rare cases, prolonged use of strong steroid creams over large areas of the body may contribute, especially in children or when used incorrectly.
4. Can Cushing’s syndrome be cured?
Many cases improve or resolve once the underlying cause is treated. The outcome depends on the specific cause and how early treatment begins.
5. Why does the face become rounder?
Excess cortisol changes how fat is distributed throughout the body, leading to fat accumulation around the face, neck, and abdomen.
6. Is Cushing’s syndrome dangerous?
Yes. If left untreated, it can increase the risk of diabetes, high blood pressure, infections, and other serious health problems.
7. Should I stop taking my steroid medicine if I develop symptoms?
No. Steroid medicines should never be stopped suddenly. Speak with a healthcare provider, who can advise whether the dose needs to be adjusted safely.
Conclusion
Cushing’s syndrome is a condition caused by long-term exposure to excessive cortisol. In Uganda, the most common cause is prolonged steroid treatment, although tumours and other medical conditions can also be responsible. Recognising symptoms early and seeking medical advice can help prevent complications. With proper diagnosis, careful monitoring, and appropriate treatment, many people experience significant improvement and can regain their health.
