Symptoms of gestational diabetes

Gestational diabetes refers to abnormal glucose tolerance that occurs during pregnancy. It usually involves only mild, asymptomatic hyperglycemia without the typical symptoms of diabetes such as dry mouth, excessive thirst, frequent urination, and weight loss. However, significant increases in blood sugar can lead to symptoms such as dry mouth, excessive thirst, frequent urination, and weight loss. It is important to be vigilant for gestational diabetes in patients who exhibit symptoms such as excessive amniotic fluid, a large fetus, or recurrent urinary tract infections. Therefore, it is generally recommended for pregnant patients to complete an OGTT (Oral Glucose Tolerance Test) by the 24th week of pregnancy to confirm whether they have gestational diabetes. After childbirth, blood sugar levels in women with gestational diabetes generally return to normal, but the risk of developing Type 2 diabetes in the future significantly increases. Therefore, patients with gestational diabetes should undergo diabetes screening 6 to 12 weeks postpartum and be monitored over the long term.

Hashimoto's thyroiditis diagnostic indicators

Hashimoto's thyroiditis is a type of autoimmune thyroiditis, which can present in various phases regarding thyroid function, manifesting as hyperthyroidism, hypothyroidism, or normal thyroid function. Therefore, for patients with Hashimoto's thyroiditis, it is necessary to check thyroid function to understand its status. Since Hashimoto's thyroiditis is an autoimmune thyroiditis, the thyroid peroxidase antibodies and thyroglobulin antibodies are generally elevated. Additionally, it is necessary to perform thyroid ultrasound to assess the thyroid's condition. For some difficult-to-distinguish patients, a further examination such as a 131I uptake test can be conducted, where the uptake rate in Hashimoto's thyroiditis is reduced. Even further, a fine needle aspiration biopsy of the thyroid can be performed, where we can observe significant lymphocyte infiltration.

Gestational diabetes screening time

The screening time for gestational diabetes refers to all pregnant women undergoing a 75-gram glucose tolerance test between 24 to 28 weeks of pregnancy to measure blood sugar levels and determine the presence of gestational diabetes. However, for pregnant women at high risk, including those with a history of gestational diabetes, delivery of a large fetus, obesity, polycystic ovary syndrome, a family history of diabetes, positive urinary glucose in early pregnancy, or unexplained recurrent miscarriages, fetal malformations, stillbirths, or even a history of childbirth with neonatal respiratory distress syndrome, blood sugar should be monitored as early as possible to understand the situation.

How to reduce blood sugar in gestational diabetes

Gestational diabetes cannot be treated with oral medications, as they can affect the fetus. Currently, the main treatment for gestational diabetes in China is insulin, with options for short-acting or rapid-acting insulin. If fasting blood glucose is high, long-acting insulin can be used to control fasting blood glucose levels. If post-meal blood glucose is high, short-acting or rapid-acting insulin can be used to control post-meal blood glucose levels. The blood glucose control standards for gestational diabetes are fasting blood glucose between 4.0 and 5.3, and two hours post-meal blood glucose between 4.4 and 6.7.

High-risk factors for gestational diabetes

High-risk factors for gestational diabetes include: women older than 35 years, those with a history of gestational diabetes, history of delivering large babies, obesity, patients with polycystic ovary syndrome, first-degree relatives with a family history of diabetes, early pregnancy checks showing fasting hyperglycemia or positive glucosuria, patients who have had multiple spontaneous miscarriages without obvious causes, fetal malformations, stillbirths, and patients with a history of delivering newborns with respiratory distress syndrome. Women with the above high-risk factors should undergo early testing for fasting blood glucose and a 75-gram glucose tolerance test to diagnose gestational diabetes and initiate early intervention.

Can Hashimoto's thyroiditis patients eat iodized salt?

Hashimoto's thyroiditis is an autoimmune thyroid disease, which can manifest in three thyroid function states: hyperthyroidism, euthyroidism, and hypothyroidism. The dietary requirements for iodized salt vary depending on the thyroid state. When Hashimoto's thyroiditis coexists with hyperthyroidism, an iodine-restricted diet is necessary. When thyroid function is normal in Hashimoto's thyroiditis, iodine intake should still be limited, as excessive iodine can cause a thyroiditis that changes from euthyroid to dysfunctional. Therefore, iodized salt can be consumed, but the intake of iodine-rich foods such as kelp, seaweed, and seafood should be restricted. When Hashimoto's thyroiditis coincides with hypothyroidism, iodized salt can be consumed without specific restrictions; both iodized and non-iodized salt are acceptable. This is because, at this stage, thyroid function primarily requires hormone replacement therapy, so the consumption of iodized salt has no effect.

Impact of gestational diabetes on the fetus and pregnant women

The effects of gestational diabetes on the mother mainly include an increased risk of miscarriage, concurrent conditions such as gestational hypertension and preeclampsia, as well as the potential for diabetic ketoacidosis. The presence of a large fetus can lead to difficult labor, damage to the birth canal, prolonged surgical delivery, and an increased likelihood of postpartum hemorrhage. Additionally, women with gestational diabetes have an increased risk of developing the condition again in future pregnancies. In terms of long-term effects, the risk of developing type 2 diabetes significantly increases after experiencing gestational diabetes. For the fetus, the impacts of gestational diabetes primarily manifest as an increased risk of spontaneous miscarriage, congenital anomalies, and abnormal development. There is also a heightened risk of hyperinsulinemia, which can even affect the proper development and maturity of the fetal lungs, leading to delays. After birth, conditions such as hypoglycemia and neonatal respiratory distress syndrome are more likely to occur. In the long term, offspring of women with gestational diabetes are at higher risk for glucose intolerance, diabetes, obesity, and metabolic syndrome. These conditions significantly increase the risks to the cardiovascular system and can affect neuromotor development.

Foods to avoid with thyroid cysts

For patients with thyroid cysts, it is necessary to first understand the patient's thyroid function, whether it is normal, overactive, or underactive. For patients with thyroid cysts who also have hyperthyroidism, a diet avoiding iodine is still necessary, as excessive iodine intake can significantly affect their hyperthyroid condition, therefore they need to consume iodine-free food. However, for patients with normal thyroid function or those with hypothyroidism, a normal diet is appropriate, and there is no need to avoid iodine. It is also recommended that they avoid smoking and alcohol in their daily life.

Do thyroid cysts require medication?

Patients with thyroid cysts who have normal thyroid function do not need oral medication treatment; they only need regular monitoring of thyroid function and thyroid ultrasound. However, patients with thyroid cysts accompanied by hyperthyroidism need to be treated for hyperthyroidism, either with oral medication, iodine-131, or surgery. When thyroid cysts are accompanied by hypothyroidism, oral hormone replacement treatment is also required to bring the thyroid function back to normal levels. Therefore, whether patients with thyroid cysts need medication depends on the results of their thyroid function tests.

Is thyroiditis contagious?

Thyroiditis, based on its cause, can be classified into subtypes such as subacute thyroiditis and autoimmune thyroiditis. Subacute thyroiditis is primarily caused by viral infections leading to the destruction of the thyroid follicular structure, and it is not contagious. Autoimmune thyroiditis primarily involves the presence of autoantibodies within the body, which lead to the destruction of thyroid follicles and consequently to the apoptosis of thyroid cells. This cause is also non-contagious. Therefore, thyroiditis cannot be transmitted, but it does have genetic susceptibility. For patients whose parents have thyroiditis, their children may also have thyroiditis.
