Keto Diet: A Potential Treatment Option For Cushing's Syndrome?

Cushing's syndrome is a rare disorder characterised by high levels of cortisol in the blood, which can lead to a host of health issues, including excess fat in the face and midsection, hypertension, diabetes, and infertility. While it is often associated with poor lifestyle choices, Cushing's can also be caused by excess corticosteroid medication, or a tumour on the pituitary or adrenal glands.

A ketogenic diet has been found to ease the symptoms of Cushing's, but it may also delay diagnosis and treatment. A low-carbohydrate, high-fat diet can help with weight loss, and when paired with other treatments, it may help to limit or counteract some symptoms of Cushing's. However, it is important to note that the ketogenic diet may initially mask the symptoms of Cushing's, making it more difficult to diagnose and treat effectively.

How does Cushing's Disease affect the body?

Cushing's syndrome, or hypercortisolism, is a severe disorder that occurs when the body produces too much of the hormone cortisol over a long period of time. Cortisol is sometimes called the ""stress hormone"" because it is released during stressful or frightening situations, triggering a "fight-or-flight" response in the body.

Cushing's syndrome can be caused by several factors, including the long-term use of corticosteroid medications, such as prednisone, to treat inflammatory diseases or to prevent organ rejection after a transplant. It can also be caused by tumours on the pituitary or adrenal glands, which affect the body's ability to regulate cortisol levels. The condition is rare, affecting an estimated 40 to 70 people out of every million.

The symptoms of Cushing's syndrome vary but often include weight gain, particularly in the midsection and face, resulting in a round, moon-shaped face. Other signs may include:

• Purple stretch marks on the breasts, arms, abdomen, and thighs
• Thinning and fragile skin that bruises easily and heals slowly
• High blood pressure (hypertension)
• Increased infections
• Irregular or absent menstrual periods
• Body and facial hair growth in women (hirsutism)
• Decreased libido, infertility, and erectile dysfunction in men

Left untreated, Cushing's syndrome can lead to serious health complications, including:

• Heart attack or stroke
• Blood clots in the legs and lungs
• Bone loss and fractures
• Unhealthy cholesterol levels
• Depression or other mood changes
• Memory loss or trouble concentrating
• Insulin resistance and prediabetes

The treatment for Cushing's syndrome aims to lower cortisol levels in the body and depends on the underlying cause. Medications may be prescribed to decrease cortisol production or block its effects on the body. In some cases, surgery, radiation, or chemotherapy may be necessary to remove or treat tumours.

What are the symptoms of Cushing's?

Cushing's syndrome, also known as hypercortisolism, is a hormonal disorder where the body has high levels of the hormone cortisol over a long period. Cortisol is a steroid hormone, commonly referred to as the "stress hormone", and is produced by the adrenal glands. It is responsible for several functions in the body, including increasing heart rate and blood pressure, managing blood glucose, and managing respiration.

The symptoms of Cushing's syndrome vary but can include:

• Weight gain, particularly in the face, resulting in a "moon face" appearance
• Weight gain in the abdomen, back of the neck ("buffalo hump"), and chest
• High blood pressure (hypertension)
• Fragile skin that bruises easily and wounds that heal slowly
• Stretch marks, particularly on the midsection, upper legs, breasts, and arms
• Excessive hair growth on the face, neck, chest, abdomen, breasts, and thighs, or balding
• Fatigue
• Blurry vision and dizziness
• Weak and thinning muscles
• Libido changes and erectile dysfunction
• Irregular or absent periods in women

Cushing's syndrome can often be mistaken for other conditions, such as polycystic ovary syndrome or metabolic syndrome, so it is important to consult a doctor for an accurate diagnosis.

What are the dietary recommendations for Cushing's?

Cushing's syndrome is a severe disorder characterised by high levels of cortisol in the blood, which can lead to serious health issues such as excess fat in the face and midsection, hypertension, diabetes, and infertility. The condition can be caused by excess corticosteroid medication, often used to treat allergies, asthma, and arthritis, or a tumour on the pituitary or adrenal glands.

A ketogenic diet has been found to help alleviate some of the symptoms of Cushing's syndrome. However, it is important to note that the diet may also delay diagnosis and should be used in conjunction with other treatments.

• Increase calcium and vitamin D intake: Cushing's syndrome can cause reduced bone density or osteoporosis. Consuming foods rich in calcium and vitamin D, such as green leafy vegetables, milk, nuts, and fortified foods, can help prevent bone breakdown and osteoporosis.
• Maintain a balanced protein intake: Muscle wastage is a common side effect of Cushing's syndrome, leading to thinner arms and legs. Eating enough protein can help maintain muscle mass, strength, and overall health. Good sources of protein include beans, lean meats, tofu, and cottage cheese.
• Reduce sodium intake: Excess sodium can worsen symptoms of Cushing's syndrome by increasing blood pressure and causing weight gain. It is recommended to cut down on processed foods and limit the amount of salt added to food.
• Control blood sugar: Cushing's syndrome can lead to high blood sugar levels, increasing the risk of diabetes. Avoiding sweets and processed foods, and eating high-fibre foods such as whole-wheat bread, oatmeal, nuts, berries, and sweet potatoes can help maintain healthy blood sugar levels.
• Reduce cholesterol: Cushing's syndrome is often associated with high cholesterol levels. Consuming less fatty foods and more high-fibre foods, such as kidney beans, apples, pears, barley, and prunes, may help offset the effects of high cholesterol.
• Reduce or eliminate alcohol and tobacco: Chronic heavy drinking can damage the hypothalamic-pituitary-adrenal (HPA) axis hormone network, resulting in symptoms similar to Cushing's syndrome. Additionally, tobacco use increases the risk of complications during surgery, which may be necessary for treatment.

Can keto help with hypertension?

Cushing's disease is a severe disorder characterised by high levels of cortisol in the blood. Cushing's can cause hypertension, and a ketogenic diet may help to manage this.

Cortisol is a steroid hormone produced in response to low blood sugar. It helps to manage blood pressure and is one of the body's fight-or-flight hormones. It is released in stressful situations, increasing heart rate and blood pressure and pumping glucose into the bloodstream for fuel.

Cushing's syndrome is caused by an excess of cortisol in the blood, which can have serious consequences, including hypertension. It can be caused by excess corticosteroid medication, or a tumour on the pituitary gland or adrenal glands.

A ketogenic diet is low in carbohydrates and high in fats. It can be used to lose weight and has been shown to improve metabolic disorders. It can also help to lower blood pressure.

A case study of a man in his thirties with Cushing's disease showed that a ketogenic diet helped him to lose weight and manage his blood pressure. He had a history of hypertension, and his blood pressure was still poorly controlled despite medication and a low-salt diet. After switching to a ketogenic diet, he lost 35 lbs over 1.5 years and his blood pressure improved.

Another study of 15 patients with Cushing's disease showed that a very low-calorie ketogenic diet (VLCKD) improved clinical, lipid and insulin sensitivity parameters. There was a significant decrease in systolic and diastolic blood pressure.

A ketogenic diet may help to manage hypertension caused by Cushing's disease by reducing weight and improving metabolic disorders. However, it is important to note that a ketogenic diet may also mask the symptoms of Cushing's disease, delaying diagnosis and treatment.

What are the risks of keto for Cushing's patients?

The keto diet may help to ease the symptoms of Cushing's disease, but it can also delay diagnosis and treatment. Cushing's disease is caused by excess cortisol in the blood, which can lead to serious health consequences such as excess fat in the face and midsection, hypertension, diabetes, and infertility. A keto diet is low in carbohydrates and high in fats, which can help to manage blood pressure and reduce inflammation and immune system response. However, there are some risks associated with the keto diet for Cushing's patients:

• Delay in diagnosis and treatment: The keto diet may ease the symptoms of Cushing's disease, leading to a delay in diagnosis and treatment. It is important to consult a doctor and not self-treat with a keto diet, as the underlying condition needs to be addressed.
• Nutritional deficiencies: Cushing's syndrome can cause nutritional deficiencies, and a keto diet may exacerbate these. It is important to ensure adequate intake of essential nutrients, especially calcium and vitamin D, to protect bone health.
• Increased blood pressure: Cushing's syndrome is associated with increased blood pressure, and a keto diet may further increase blood pressure due to the high-fat content. It is crucial to monitor blood pressure closely and make adjustments as needed.
• Weight loss challenges: While a keto diet may help with weight loss initially, long-term weight management can be challenging due to the restrictive nature of the diet. It is important to work with a healthcare professional to ensure safe and sustainable weight loss.
• Adverse effects: A keto diet may cause side effects such as constipation, headache, hunger, and fatigue. It is important to be aware of these potential side effects and consult a healthcare professional if they occur.
• Medication interactions: If medications are being used to treat Cushing's disease, a keto diet may interact with them. It is crucial to discuss any dietary changes with a doctor to ensure the safety and effectiveness of the treatment plan.
• Surgical complications: If surgery is required to treat Cushing's disease, a keto diet may impact surgical outcomes. It is important to follow the pre-operative instructions provided by the healthcare team, including any dietary restrictions.
