Families who want to have a second child often have a vision of a new life, but there is one thing that should not be overlooked before embarking on this life journey – and that is the health of the parents. As the saying goes, "the tree wants to be quiet but the wind does not stop, and the child wants to raise but does not wait". While we eagerly look forward to welcoming new family members, it is important to ignore that there are some underlying health issues that may adversely affect the birth of the next generation. This article will delve into the five diseases that must be cured before planning a second child, so as to ensure that every parent can welcome the arrival of a new life in the best physical condition. Eugenics is not an unattainable dream, but an achievable goal with the efforts of each of us. 
Abnormal glucose metabolism is not only a personal health problem, it also has a direct impact on the health of the future baby. Keeping your blood sugar within the normal range before pregnancy is a crucial step in eugenics. First, understand how abnormal glucose metabolism can affect fertility: it can lead to poor embryonic development, increase the risk of miscarriage, and even affect the future health of your baby. Therefore, it is necessary to adjust the diet, reduce the intake of high sugar, increase the amount of fiber foods, and exercise moderately, such as walking briskly for 30 minutes a day. For those who need medication**, adjusting the type and dosage of medication as directed and monitoring your blood sugar regularly are necessary steps before you prepare for pregnancy. Increased blood pressure in the systemic arteries: Stability is key High blood pressure is another health concern that needs to be addressed before pregnancy. Not only does it increase the risk of complications during pregnancy, such as pre-eclampsia, but it can also affect the health of the fetus. Ways to stabilize blood pressure include eating a healthy diet (reducing salt intake and increasing vegetable and fruit intake), regular physical activity (eg, walking, yoga), and using appropriate antihypertensive medications as directed by a doctor. It is important to monitor your blood pressure regularly to make sure it stays within the normal range. These measures not only help to improve reproductive health, but also serve as the basis for a long-term healthy life. Thyroid dysfunction: Balance first, abnormal thyroid function can affect a woman's ovulation and overall fertility, as well as fetal development. Whether it is hyperthyroidism or hypothyroidism, it needs to be properly controlled before pregnancy. Eating a proper diet, iodine-rich foods such as kelp, fish can help regulate thyroid function. At the same time, following your doctor's guidance and administering medications** to adjust thyroid hormone levels to the normal range is an important step in ensuring eugenics. Regular thyroid function checks, especially before planning a pregnancy, can ensure that thyroid status doesn't affect your health during pregnancy. Reproductive infections not only affect the health of couples, but can also have long-term effects on the health of future children. Timely identification and development of reproductive infections is an important part of eugenics. Common reproductive infections include cervicitis, pelvic inflammatory disease, prostatitis, etc., which can be silent but can pose a serious threat to fertility. Prevention Strategies: Regular health check-ups for the reproductive system, especially for families with family plans, should be taken seriously. Personal hygiene: Maintain personal hygiene and avoid using public bathrooms and swimming pools to reduce the chance of infection. Safe sex: Use safe measures to avoid the spread of sexually transmitted diseases. **Ways to seek medical attention in a timely manner: Once you find discomfort, you should seek medical attention immediately, through medication** or necessary surgical intervention, and completely ** infection. Partner treatment: For sexually transmitted infections, partner acceptance at the same time is key to prevention. 
Obesity is not only a lifestyle disease, but also a killer that affects fertility. Obesity interferes with normal reproductive function through a variety of mechanisms, including but not limited to hormonal imbalances, ovulation disorders, etc. The right path to weight loss: Eat a balanced diet: balance your nutrient intake, reduce your intake of high-calorie foods, and increase your intake of vegetables and fruits. Regular exercise: At least 150 minutes of moderate-intensity exercise per week, such as brisk walking, swimming, etc. Medical advice: For hard-to-control obesity, seek medical help and consider medical or surgical intervention. Preparing for a healthy second child is a comprehensive task that requires multiple perspectives to ensure that both spouses are in the best possible condition for the arrival of a new child. **Reproductive infections and obesity control are important steps on the road to a healthy second child. By doing so, you can not only improve fertility but also provide your child with a healthier start. 
Remember, every small change is for a bigger goal – a healthy family. Regular health check-ups, a sensible diet, moderate exercise, and an emphasis on reproductive health are the solid foundations for achieving this goal. Let's take this preparation and expectation to move towards a healthy second child together.
