Introduction
Under normal circumstances, type 1 diabetes may be caused by factors such as genetic susceptibility, unhealthy lifestyle habits, exposure to chemicals, viral infections, and autoimmune type 1 diabetes. Symptomatic management is required through general treatment and medication. During the treatment process, it is recommended to maintain a healthy lifestyle and positive mindset, which can aid in the recovery from the condition.

Generally, type 1 diabetes may be caused by factors such as genetic susceptibility, unhealthy lifestyle habits, exposure to chemical substances, viral infections, and autoimmune type 1 diabetes. Symptomatic management through general treatment and medication is required. If physical discomfort occurs, prompt medical consultation and treatment are advised. Detailed analysis is as follows:

1. Genetic Susceptibility

Certain specific gene variations may make individuals more prone to developing type 1 diabetes. These genetic variations may affect the normal functioning of the immune system, making it more likely to attack pancreatic beta cells. Regular monitoring of blood glucose levels and maintaining a healthy lifestyle can effectively manage diabetes symptoms.

2. Unhealthy Lifestyle Habits

Long-term high-sugar and high-fat diets, lack of physical activity, and other unhealthy lifestyle habits may damage pancreatic beta cells, increasing the risk of developing type 1 diabetes. Symptoms of metabolic syndrome such as obesity, hypertension, and hyperlipidemia may occur. It is recommended to improve dietary habits, reduce intake of high-sugar and high-fat foods, and increase consumption of dietary fiber and protein.

3. Exposure to Chemical Substances

Long-term exposure to certain chemicals or toxic substances, such as rodenticides, may damage pancreatic beta cells, thereby triggering type 1 diabetes. Symptoms of poisoning after exposure to these chemicals may include nausea, vomiting, and dizziness. It is recommended to immediately leave the environment with chemical exposure and avoid exposure to harmful substances to reduce the risk of type 1 diabetes.

4. Viral Infections

Certain viral infections, such as mumps virus, rubella virus, and Coxsackie virus, may trigger an autoimmune response after infecting the body, leading to damage of pancreatic beta cells. General viral infection symptoms such as fever, fatigue, and muscle pain may also occur. It is recommended to use medications such as metformin hydrochloride sustained-release tablets, nateglinide tablets, and tianmaikang granules under a doctor's guidance for treatment.

5. Autoimmune Type 1 Diabetes

Patients with type 1 diabetes often have autoantibodies targeting pancreatic beta cells. These abnormal antibodies mistakenly attack and destroy pancreatic beta cells, leading to impaired or complete loss of insulin secretion function, resulting in hyperglycemia. Other symptoms of autoimmune diseases, such as thyroid disease and adrenal insufficiency, may also be present. It is recommended to follow medical advice and use medications such as acarbose capsules, glimepiride tablets, and gliquidone tablets to alleviate symptoms.

During the treatment process, it is recommended to maintain good lifestyle habits and a positive mindset, which can aid in recovery.

Can people with type 1 diabetes drink plain boiled water?
If a patient with diabetes does not have heart failure or chronic kidney disease, it is recommended to drink ample plain water. Increased intake of plain water helps regulate blood glucose levels and promotes metabolism. In diabetic patients, elevated blood glucose leads to increased blood viscosity; prolonged hyper-viscosity significantly raises the risk of macrovascular complications—such as cerebral infarction and myocardial infarction. Adequate fluid intake is therefore essential for diabetic patients.

Which is more severe, type 1 or type 2 diabetes?
Type 1 diabetes refers to diabetes mellitus type 1. Compared to type 2 diabetes, type 1 is more severe. Type 1 diabetes is caused by the destruction of insulin-producing cells, leading to persistently elevated blood glucose levels. Type 2 diabetes is a condition resulting from insulin resistance. Type 1 diabetes can lead to life-threatening ketoacidosis, whereas type 2 diabetes generally does not affect lifespan.

Symptoms of type 1 diabetes
Type 1 diabetes is a metabolic disorder primarily caused by the destruction of pancreatic beta cells, leading to an absolute deficiency of insulin and resulting in elevated blood glucose levels. Its symptoms include the preclinical stage, initial onset stage, and mid-to-late stages of diabetes. Typical symptoms mainly include polydipsia (excessive thirst), polyuria (frequent urination), polyphagia (increased hunger), and weight loss, accompanied by discomforts such as fatigue, nausea, and vomiting.

Can people with type 1 diabetes consume protein powder?
Type 1 diabetes patients should not consume protein powder. This is because type 1 diabetes carries a high risk of developing diabetic nephropathy; therefore, additional protein intake increases the burden on the kidneys and may cause some degree of renal damage. Consequently, protein powder is not recommended for type 1 diabetes patients who already have diabetic nephropathy as a complication. In contrast, for type 2 diabetes patients without significant diabetic complications, protein powder use may be considered—but only under appropriate medical guidance.

Symptoms of Type 1 Diabetes in Children
After developing type 1 diabetes, children may initially experience increased appetite, often accompanied by marked polydipsia (excessive thirst). As the disease progresses, affected children may also develop polyuria (increased urinary frequency), nocturia (frequent urination at night), and enuresis (bedwetting). Despite increased food and fluid intake, body weight does not increase; instead, progressive weight loss may occur.

Can individuals with type 1 diabetes drink infant formula?
It is not recommended for people with diabetes to consume powdered milk. Generally, powdered milk is discouraged for individuals with diabetes because it can cause a rapid and significant rise in blood glucose levels, making glycemic control difficult and leading to greater fluctuations—thereby increasing the risk of diabetes-related complications, such as cardiovascular and cerebrovascular diseases. Powdered milk may be consumed only when dietary intake is restricted and independent oral feeding is not possible.

Can patients with type 1 diabetes consume American ginseng?
Patients with type 1 diabetes may consume American ginseng, which offers certain health benefits for individuals with diabetes. American ginseng possesses blood glucose–regulating properties and can help stabilize the condition of diabetic patients. When consumed in moderation as part of diabetes management, it may also enhance overall physical strength. Additionally, American ginseng can help alleviate symptoms such as thirst and dry throat commonly experienced by diabetic patients.

Can patients with type 1 diabetes drink mugwort leaf tea on an empty stomach?
Patients with type 1 diabetes may drink mugwort leaf tea on an empty stomach. Mugwort leaf is a traditional Chinese herbal medicine; however, patients with diabetes must use it only under the guidance of a qualified TCM practitioner. Traditional Chinese medicine classifies herbs according to their “four natures” and “five flavors,” and herbal prescriptions should be individualized based on syndrome differentiation and the patient’s specific constitution. Inappropriate use of herbal medicines may not only lack therapeutic effect but also cause harm to the body. Mugwort leaf, as a single herb, is warm in nature and bitter in taste, and primarily influences the Liver, Spleen, and Kidney meridians.
