Question

discuss how infection and nutrition can delay wound healing.

Answer 1

Wound healing, as a normal biological process in the human body, is achieved through four precisely and highly programmed phases: hemostasis, inflammation, proliferation, and remodeling.For a wound to heal successfully, all four phases must occur in the proper sequence and time frame.

There are several factors that delay the process of wound healing like the oxygenation,infection,age and sex hormones, stress, diabetes, obesity, medications, alcoholism, smoking, and nutrition.

• Nutrition has been recognized as a very important factor
• that affects wound healing.Most obvious reason is that malnutrition or specific nutrient deficiencies can have a profound impact on wound healing after trauma and surgery.
• Patients with chronic or non-healing wounds and experiencing nutrition deficiency often require special nutrients.
• Energy, carbohydrate, protein, fat, vitamin, and mineral metabolism all can affect the healing process.
• The state of infection and replication status of the micro-organisms also determines whether the wound is classified as having contamination, colonization, local infection or critical colonization, and spreading invasive infection.
