Allergic purpura is an immune system disorder, primarily manifested as skin purpura, joint pain, abdominal pain, and kidney damage. A proper diet can help improve symptoms and promote recovery.

It is recommended to choose foods rich in fiber, such as vegetables, fruits, and legumes, including spinach, carrots, broccoli, cauliflower, apples, and others, which help enhance intestinal health and reduce the growth of harmful bacteria. Whole grains such as oats, whole wheat bread, and brown rice are rich in dietary fiber and vitamin B, providing sustained energy for the body.

Increase intake of foods rich in vitamins C and E, such as citrus fruits, kiwifruit, spinach, nuts, and seed oils. These nutrients have antioxidant effects that can reduce inflammation and promote vascular health. Cod liver oil, as a good source of vitamins A and D, helps support immune system function and skin health.

Maintaining adequate hydration is beneficial for kidney detoxification and overall health. While adjusting their diet, patients should follow medical advice, have regular follow-up examinations, and monitor changes in their condition.

For small bumps appearing on the hands and legs accompanied by itching, the first step is to determine the underlying cause. This may be due to various factors such as allergic reactions, eczema, urticaria, or other skin conditions.

Antihistamines, such as cetirizine and loratadine, can effectively relieve symptoms of skin itching and swelling. They provide good itch relief for various skin conditions including urticaria, eczema, and neurodermatitis. Mild to moderate inflammation can be treated with low- or mid-potency corticosteroid creams or ointments, such as hydrocortisone.

For dry skin conditions, the use of moisturizing creams or lotions can help alleviate symptoms. Depending on the specific cause, oral medications such as chlorpheniramine maleate tablets, vitamin A soft capsules, or vitamin E soft capsules may be required to assist in treatment or symptom relief.

Medications must be strictly used according to medical instructions; self-purchase and use are strongly discouraged. Maintaining good personal hygiene, avoiding contact with irritants, and wearing breathable clothing are also important preventive and supportive treatment measures.

Swelling, pain, and lumps in the jaw area can be caused by various factors, such as insect bites, folliculitis, lymphadenitis, acne, or lipomas.

The lymph nodes in the neck are common sites of reactive changes following infections. When an infection occurs in a certain part of the body, the corresponding lymph nodes may swell and become painful. Some benign or malignant tumors may also present as lumps in the neck, such as lipomas or thyroid tumors. These conditions may not cause significant pain but may gradually increase in size.

For mild redness, swelling, and pain during the acute phase, cold compresses may be considered to constrict capillaries and reduce the inflammatory response. Apply cold compresses for 5 to 10 minutes each time. Avoid squeezing the affected area to prevent worsening of inflammation or spread of infection. For localized discomfort caused by allergies, antihistamines can help relieve itching and swelling.

Patients are advised to seek timely medical attention for a detailed medical history, physical examination, and necessary imaging studies such as ultrasound or CT scan, to establish an accurate diagnosis. The treatment plan will be formulated based on the specific cause and may include medication, surgical removal, or other appropriate therapies.

Rapid elimination of acne requires a comprehensive approach. First, drug therapy is essential. Commonly used medications include retinoic acid-based ointments, such as adapalene gel, which can improve symptoms of follicular keratinization in sebaceous glands and possess certain anti-inflammatory effects.

Topical application of creams containing benzocaine, salicylic acid, or benzoyl peroxide can also help. These ingredients aid in reducing inflammation and controlling sebum production. For severe cases, oral antibiotics or retinoic acid medications might be necessary, although they should be used under a doctor's supervision. Blue and red light therapies effectively kill Propionibacterium acnes, reduce inflammation, and promote skin healing.

In daily life, it is recommended to reduce the intake of high-sugar and high-fat foods while increasing consumption of vegetables and fruits to maintain a healthy diet. Acne may worsen under high stress, so appropriate exercise and relaxation can positively improve skin conditions.

Daily skincare is also important. Keeping the skin clean, avoiding squeezing pimples with hands, and maintaining a light diet all contribute to the rapid elimination of acne.

Psoriasis is a chronic skin condition with various treatment options, mainly including pharmacological therapy, physical therapy, and traditional Chinese medicine therapy.

Pharmacological treatment involves the use of topical medications, such as corticosteroids, retinoids, and calcineurin inhibitors, to reduce inflammation and promote normalization of the epidermis. Biologic agents, such as adalimumab and infliximab, are administered via injection or intravenous infusion to target specific cytokines, thereby reducing inflammation and suppressing immune responses.

Phototherapy involves exposing the skin to ultraviolet light of specific wavelengths, such as PUVA therapy, to alleviate symptoms. Excimer laser treatment is suitable for mild to severe psoriasis, targeting affected skin areas without damaging healthy skin. Herbal remedies based on traditional Chinese medicine, such as formulas with heat-clearing, detoxifying, blood-activating, stasis-resolving, wind-dispelling, and dampness-removing properties, may also be used for treatment.

Patients should maintain healthy lifestyle habits and avoid triggering factors such as stress, infections, alcohol consumption, and smoking. Regular follow-up visits and timely adjustments to treatment plans according to disease progression are essential for effective psoriasis management.

In general, the development of type 2 diabetes has clear stages, which can be simply divided into prediabetes and clinical diabetes stages.

Prediabetes refers to blood glucose levels higher than normal but not meeting the diagnostic criteria for diabetes. It includes impaired fasting glucose (fasting blood glucose 6.1–6.9 mmol/L) and impaired glucose tolerance (2-hour blood glucose 7.8–11.0 mmol/L after glucose loading). This stage represents a critical period for prevention, and some individuals may also have obesity, dyslipidemia, and other problems.

In the clinical diabetes stage, early on is mainly characterized by insulin resistance, with compensatory insulin secretion and no obvious symptoms; lifestyle interventions and medications targeting insulin resistance are the main treatment approaches. In the middle stage, insulin secretion becomes insufficient to compensate for the resistance, leading to gradually rising blood glucose levels and the emergence of symptoms such as polydipsia, polyphagia, polyuria, and weight loss. In the late stage, pancreatic beta cells are severely damaged, with near absence of insulin secretion, requiring exogenous insulin to maintain blood glucose control. Patients are prone to develop acute complications such as diabetic ketoacidosis or hyperosmolar hyperglycemic syndrome.

A deviated nasal bridge may be caused by congenital factors, acquired trauma, pathological factors, or others. If experiencing discomfort, timely medical consultation is recommended.

During embryonic development, uneven growth of the nasal bones, nasal septal cartilage, or surrounding soft tissues may lead to a deviated nasal bridge. For example, nasal septal deviation often accompanies a deviated nasal bridge; some people are born with this condition, which may be related to genetic factors or environmental influences during pregnancy, such as medication exposure or nutritional deficiencies.

This is one of the main causes of a deviated nasal bridge. External nasal trauma, such as injuries from sports, traffic accidents, or physical altercations, can cause nasal bone fractures, dislocation or twisting of the nasal septal cartilage. If the nasal structures do not heal properly after injury, a deviated nasal bridge may remain. For example, nasal trauma during adolescence that is not promptly treated may gradually become apparent as the individual grows and develops.

Certain diseases may indirectly cause nasal bridge deviation. For instance, intranasal tumors such as hemangiomas or nasal polyps exerting long-term pressure on the nasal septum may cause displacement. Chronic rhinitis or sinusitis causing prolonged inflammation may affect the nasal septal cartilage, leading to structural deformation. Additionally, rare congenital nasal bone malformations may also present with nasal bridge deviation.

A deviated nasal bridge not only affects appearance but may also lead to functional problems such as nasal obstruction, headache, and reduced sense of smell in severe cases. If the deviation is mild and asymptomatic, no immediate treatment may be necessary. However, if the deviation is pronounced or accompanied by symptoms, diagnostic evaluation using nasal bone CT scans, nasal endoscopy, and other tests should be performed to determine the underlying cause. Surgery, such as nasal bone correction, septoplasty, or rhinoplasty, may be required to correct the condition when indicated.

In general, pregnant women can eat oranges, but they should consume them in moderation.

Oranges are rich in vitamin C. During pregnancy, a woman's nutritional needs increase, and vitamin C can enhance the expectant mother's immunity, helping the body resist external pathogens and reduce the likelihood of illness during pregnancy. Pregnant women are prone to iron-deficiency anemia, and the vitamin C in oranges can promote iron absorption. Iron is an essential component for producing hemoglobin, which transports oxygen to various parts of the body. Sufficient iron intake ensures the fetus receives adequate oxygen and nutrients, promoting normal fetal growth and development.

Many pregnant women experience nausea and vomiting during early pregnancy and may have a poor appetite. The sweet and sour taste of oranges can stimulate the taste buds, increase appetite, and alleviate discomfort caused by morning sickness. Just like when having a poor appetite, eating some sour and sweet oranges can make one feel more inclined to eat. However, moderation is important, as oranges contain significant amounts of citric acid, which may irritate the gastrointestinal mucosa if consumed in excess. During pregnancy, digestive function is relatively weaker, and excessive orange consumption may lead to excessive gastric acid secretion, causing discomfort symptoms such as stomach pain, bloating, and acid reflux.

Pregnant women should also check if they are allergic to oranges before consuming them. If a pregnant woman is allergic to components in oranges, she may experience symptoms such as skin itching and swelling after consumption and should therefore avoid eating oranges. During pregnancy, it is important to maintain a balanced diet, avoid excessively cold, spicy, or irritating foods, and maintain good lifestyle habits to support the healthy development of the fetus.

Generally speaking, pregnant women can eat zongzi (glutinous rice dumplings), but they should pay attention to controlling their intake. The specific analysis is as follows:

Zongzi are mostly made from glutinous rice, which is rich in carbohydrates and serves as an important source of energy for the human body. During pregnancy, a woman's body consumes more energy and requires sufficient energy to sustain both her own health and the growth and development of the fetus. Eating zongzi in moderation can provide pregnant women with adequate energy to help maintain good mental condition and physical strength.

Zongzi come in a variety of fillings, such as red dates, red bean paste, salted egg yolk, and meat. Red dates are rich in vitamin C, iron, and other nutrients, and have the effect of nourishing the blood and improving complexion. For pregnant women who are prone to anemia, eating zongzi filled with red dates in moderation can help prevent and improve anemia. Red bean paste contains abundant protein and dietary fiber, which can promote intestinal motility and prevent constipation. Salted egg yolks and meat are rich in high-quality protein, fat, vitamins, and minerals, which are highly beneficial for fetal brain development and physical growth.

However, it is important to eat zongzi in moderation. Digestive function in pregnant women is relatively weak during pregnancy, and excessive consumption of zongzi may increase the burden on the gastrointestinal tract, leading to indigestion and symptoms such as abdominal distension, abdominal pain, nausea, and vomiting. If any discomfort occurs, medical advice should be sought promptly. While enjoying traditional delicacies, pregnant women should also ensure the health and safety of both themselves and the fetus.
