Feeling tired even after waking up in the morning, persistent weakness, and weight loss without dieting—these symptoms are often dismissed as work stress, lack of sleep, or dietary irregularities. However, in some cases, they may also be a sign of cortisol deficiency. Cortisol is an essential hormone that helps the body cope with stress, regulate blood sugar, and maintain blood pressure.
When the adrenal glands don’t produce enough cortisol, the condition is called adrenal insufficiency. This can lead to fatigue, muscle weakness, loss of appetite, and weight loss. Let’s understand how cortisol deficiency affects the body.
According to the NIDDKD, cortisol is commonly known as the stress hormone. It is produced in the adrenal cortex, the outer layer of the adrenal glands located above the kidneys. This hormone plays a role in controlling many vital body processes. It also plays a vital role in providing the body with additional energy during situations like stress, illness, or injury.
An important function of cortisol is to help regulate blood sugar. It contributes to providing the body with the energy it needs, regulating metabolism and immune system function. It also helps maintain blood pressure and control inflammatory responses in the body. Its levels do not remain constant throughout the day. It is typically higher in the morning and lower at night.
Feeling constantly tired does not necessarily mean a lack of cortisol in the body. Fatigue is a common symptom that can appear in many health problems. Lack of sleep, anemia, thyroid problems, diabetes, infections, nutritional deficiencies, and mental stress can also cause persistent fatigue.
According to Science Direct, however, if fatigue is accompanied by muscle weakness, loss of appetite, abdominal pain, dizziness, and unexplained weight loss, testing for adrenal insufficiency may be considered. Symptoms in this condition can develop gradually, so a person may mistake them for general weakness for a long time.
Cortisol helps provide energy to the body and maintain normal blood pressure. When levels drop below the required level, normal body function can be affected.
Feeling low on energy: Cortisol contributes to blood sugar regulation. According to the NIH, a deficiency can make it difficult for the body to maintain normal blood glucose levels. Some people may also experience an increased risk of hypoglycemia, a condition characterized by low blood sugar. This can cause symptoms such as fatigue, shakiness, sweating, and weakness.
Muscle weakness: Adrenal insufficiency can make it difficult for a person to perform normal activities. Climbing stairs, standing for long periods, or performing everyday tasks may become difficult. This weakness isn’t limited to fatigue; muscle strength may also be reduced.
Low blood pressure: According to the Cleveland Clinic, especially in primary adrenal insufficiency, there may be a deficiency of the hormone aldosterone along with cortisol. Aldosterone helps maintain sodium and water balance in the body. A deficiency can disrupt the body’s salt and water balance, leading to low blood pressure. A person may feel dizzy when standing up from sitting or lying down.
According to MayoClinic, if you notice persistent weight loss without dieting or increasing exercise, it should not be ignored. Common symptoms of adrenal insufficiency include loss of appetite, stomach discomfort, and weight loss.
Cortisol deficiency can affect the body’s metabolism and energy balance. It can also cause problems like nausea, vomiting, stomach pain, or diarrhea. These problems can cause a person to feel less hungry and reduce their food intake. Long-term lack of adequate nutrition can lead to weight loss.
Cortisol deficiency can affect the body’s energy, blood sugar, blood pressure, and appetite. Persistent fatigue, muscle weakness, and weight loss without dieting are possible signs. However, these symptoms can also be seen in other diseases. Therefore, instead of self-diagnosing cortisol deficiency or taking medication, it is important to seek medical advice and seek proper treatment.
