The causes of hypoglycemia in women can be related to various factors, including drug-induced, hepatic, pancreatic, non-pancreatic tumors, renal, endocrine issues, as well as excessive consumption or insufficient intake, among others. For women, apart from organic lesions, common causes include excessive hunger, intense exercise, or chronic diarrhea, which can lead to hypoglycemia. Some women experience hypoglycemia due to lactation or pregnancy without timely replenishment of energy. Additionally, a common condition seen in women is idiopathic functional hypoglycemia, often found in neurotic women, which typically presents with symptoms of hunger and sweating, usually with few physical signs. Characteristically, it involves early-occurring reactive hypoglycemia that generally resolves on its own in less than 30 minutes, with blood glucose tests showing slightly decreased levels and normal or slightly elevated insulin levels in the blood.

How to check for hypoglycemia

We usually diagnose hypoglycemia based on the following three criteria. The first is the presence of hypoglycemic symptoms, such as palpitations, tremors, sweating, dizziness, etc. If these symptoms are present, we must immediately consider the possibility of hypoglycemia, and then proceed to monitor blood glucose levels. If the blood glucose reading is below 2.8 for non-diabetic patients and below 3.9 for diabetic patients, hypoglycemia can be considered. Subsequently, the patient should consume sugary water, and if the symptoms significantly alleviate after this, a diagnosis of hypoglycemia can be established. Moreover, if the patient does not have a history of diabetes, does not use hypoglycemic drugs, but experiences recurring episodes of hypoglycemia, further testing is required, such as a fasting test, checking C-peptide levels, insulin levels, etc., to rule out insulinoma.

How to treat hypoglycemia?

First, we need to accurately identify what hypoglycemia is. We often judge the occurrence of hypoglycemia based on symptoms, such as common symptoms including palpitations, dizziness, pale complexion, general weakness, trembling limbs, sweating, etc. When these symptoms appear, we should immediately use a rapid glucose meter to measure the fingertip blood sugar. If the blood sugar is below 2.8, then the diagnosis of hypoglycemia is confirmed. We immediately provide sugary drinks or other forms of energy substances, and the symptoms of low blood sugar can be greatly relieved.

Hypoglycemia emergency treatment procedure

Typically, when we consider a patient might have hypoglycemia, we follow the standard diagnostic procedures. First, we measure the patient's blood sugar level; if it is below 2.8 mmol/L, there is a high likelihood of hypoglycemia. Symptoms may include palpitations, dizziness, pale complexion, lack of concentration, lethargy, or even coma. Immediate action would involve giving the patient oral glucose solution or administrating glucose intravenously, followed by monitoring the patient’s clinical symptoms and blood sugar levels. If the patient's condition significantly improves after glucose provision, we can diagnose them with hypoglycemia. This is also a critical emergency procedure for hypoglycemia, which entails timely glucose supplementation. If the patient has recurrent hypoglycemia episodes, further detailed examinations should be conducted.

Hypoglycemia is caused by what?

Hypoglycemia is most commonly seen in patients with type 2 diabetes. During the treatment of diabetes, hypoglycemia can occur due to excessive use of medication or insulin, failure to eat on time after exercise, or decreased appetite without appropriately reducing the medication. Another common cause is insulinoma, a type of tumor that secretes excessive insulin, resulting in lowered blood glucose levels. A third cause relates to the early stage of type 2 diabetes, where insulin resistance and delayed insulin peak times often lead to pre-meal hypoglycemia, especially before lunch and dinner. Lastly, hypoglycemia is also commonly observed in some young women with specific coloring, potentially due to gastrointestinal motility issues or other reasons leading to pre-meal hypoglycemia. It is also common in patients with hepatitis or cirrhosis, where the liver's ability to output glucose is diminished, increasing the risk of hypoglycemia when fasting.

Can people with hypoglycemia eat mutton?

The definition of hypoglycemia is when the blood glucose level is monitored to be less than 2.8 mmol/L, or less than 3.9 mmol/L for diabetics, accompanied by symptoms such as palpitations, cold sweats, hunger, and dizziness. These symptoms can be alleviated after eating, especially after consuming sugar water, and this condition is then referred to as hypoglycemia. Hypoglycemia is classified into mild, moderate, and severe degrees. For mild hypoglycemia, with only mild symptoms, it is acceptable to eat lamb, beef, pork, or consume sugar. However, in cases of more severe hypoglycemia, where there are changes in consciousness or symptoms like somnolence, eating meat may not be quick enough. The most recommended treatment is to drink sugar water directly or to administer glucose intravenously to correct the blood sugar rapidly. This is because eating lamb, which is protein, requires digestion and absorption, and raises blood sugar levels more slowly. In cases of severe hypoglycemia, the most direct treatments are drinking sugar water or administering it intravenously.
