Wound healing timeline -
Each of these phases is defined by its vital chemical processes, which work to maintain the individual's well-being by regenerating their damaged cells. In cases where a wound is serious, blood clotting and tissue regeneration occur, leading to a scar. Every scar serves as a reminder of the various biochemical processes that go into wound healing and tissue repair.
Continue reading to learn more about the four stages of wound healing and to discover a clinically-proven method for reducing the appearance of scars. Historically, scientists only recognized three phases of wound healing : inflammation, proliferation, and maturation.
It should be noted that these phases have been referred to by different names, depending on the writer. For example, the proliferation stage has been referred to as fibroblastic or granulation, while the maturation stage is sometimes called remodeling.
Later on, this number was changed to four as authors and doctors added the hemostasis phase occurring before inflammation. There has been some debate about this classification, as some consider hemostasis to be the preliminary part of the inflammation stage.
Overall, biochemical processes that are present in one stage can overlap with others. Therefore, it is difficult to clearly define where one phase ends and the next one begins.
The first phase of wound healing, hemostasis is a first response mechanism for injuries. Immediately after a person is wounded, the blood vessels in the damaged area constrict and tighten in order to inhibit blood flow and prevent blood loss.
This process is called vasoconstriction. Next, platelets are released, coagulating with fibrin fibrous protein at the wound site. The accumulation of platelets and fibrin forms a blood clot that keeps the broken blood vessels sealed and prevents further blood loss.
The hemostasis process can last for two days or longer. Keeping the wound covered with a bandage or gauze will facilitate hemostasis and blood clotting.
Inflammation is a biological process that is defined by blood vessel dilation, also known as vasodilation, soon after the hemostasis phase has ended. The primary objective of vasodilation is to prevent infections throughout the healing process.
During vasodilation, various enzymes and leukocytes white blood cells that are beneficial to the body enter the wound site to induce inflammation. The inflammatory stage is characterized by redness around the wounded area, swelling, pain, and heat.
This phase of the healing process can last for six days or longer. As mentioned before, the biochemical processes that take place in the inflammation stage overlap and interact with the processes of hemostasis. The third phase of wound healing, proliferation, is defined by a process called angiogenesis, the genesis of granulation tissues.
Granulation tissue is most easily defined as an extracellular matrix that consists of newly-generated connective tissues and blood vessels that are designed to replace tissues that have been damaged.

The new skin and tissue is about 80 percent as strong as it was before it was injured, per the University of Rochester Medical Center.
A large or deep cut will heal faster if your healthcare provider sutures it. This helps to make the area your body has to rebuild smaller. This is why surgical wounds typically heal faster than other kinds of wounds. Surgery cuts normally take 6 to 8 weeks to heal, according to St.
Wounds may also heal faster or better if you keep them covered. According to the Cleveland Clinic, wounds need moisture to heal. A bandage also keeps the wound cleaner. Some health conditions can cause very slow healing or stop wound healing. This can happen even if your cut is due to surgery or a medical procedure.

There are three main types of wound healing, known as primary, secondary, and tertiary wound healing. Every wound goes through various stages of healing, depending on the type of wound and its severity. Understanding these categories, as well as the steps of the wound healing process, can help people understand how best to care for a wound. Keep reading to learn more about the stages of wound healing , the different types of wound healing, and some treatment options. Primary wound healing, or primary intention wound healing, refers to when doctors close a wound using staples, stitches, glues, or other forms of wound-closing processes. Closing a wound in this way reduces the tissue lost and allows the body to focus on closing and healing a smaller-area wound rather than the larger initial wound. For example, a doctor might stitch up a large cut rather than allow the body to heal over the entire cut. Secondary wound healing, or secondary intention wound healing, occurs when a wound that cannot be stitched causes a large amount of tissue loss. Doctors will leave the wound to heal naturally in these cases. This may be more common for wounds that have a rounder edge, cover uneven surfaces, or are on surfaces of the body where movement makes stitches or other closure methods impossible. This process takes longer, which may be due to increased wound size, the risk of infection and contamination, and other factors, such as the use of certain medications. Tertiary wound healing, or healing by delayed primary closure, occurs when there is a need to delay the wound-closing process. This could be necessary if a doctor fears that they may trap infectious germs in a wound by closing it. In these cases, they may allow the wound to drain or wait for the effects of other therapies to take place before closing the wound. There are several types of wounds, depending on factors such as the source of the wound and any underlying issues that may lead to it. The type may alter how doctors treat the wound or other factors in the healing process. Wounds are typically open or closed. A closed wound is an injury that does not break the surface of the skin but causes damage to the underlying tissues. A bruise is a common example of this. On the other hand, open wounds break the surface of the skin and may also damage underlying tissues. Chronic wounds may also cause breakages in the skin that need to heal. These include bedsores, other pressure injuries, and diabetes-related ulcers. All wounds go through different healing processes, ranging from the initial wound reaction to the later stages of creating new skin. Simple wounds, such as those without extensive tissue damage or infection, take about 4—6 weeks to heal. This does not include scar tissue, however, which takes longer to form and heal. The hemostasis phase occurs as the injury happens and is the first response from the body. The wound causes blood and other fluids to leave the body. The body responds by trying to stop this flow of blood. Affected blood vessels constrict to reduce blood flow. As some research notes, platelets and thrombocytes in the blood start to clump together near the open wound, forming a fibrin network. This thickens the blood in the immediate area to help stop the bleeding. This newly formed clot also prevents germs from getting into the body. The platelets release chemicals that alert the surrounding cells to start the next process and heal the wound. There is generally some inflammation in the area, as the immune cells rush to the damaged tissue. White blood cells enter the area to start cleaning out the wound and move any waste away from the site and out of the body. The proliferative phase of wound healing occurs when the wound is stable. The combined connective tissue and blood vessels is called granulation tissue. During the remodeling phase, the internal wound is mostly healed. The process switches to creating strong skin to replace the temporary tissue in the area. Some research notes that this process occurs around 2 or 3 weeks after the injury and can last for 1 year or longer. This is the active scar tissue phase of healing. The body replaces the temporary granular tissue from the early wound with stronger scar tissue. As time goes on, the scar tissue has an increased concentration of collagen, which makes it stronger. Treatment and home care options for a wound will vary greatly based on a number of factors, such as the location of the wound, the type of wound, and any additional treatments that are necessary. Treatments may include any closures needed, antibiotics to protect the wound, and dressings, in addition to other forms of therapy. Doctors will give people regular instructions on caring for their wound as it heals, as well as regular dates for check-ups to help monitor the healing process. Learn more about how to help wounds heal faster here. Anyone who is uncertain about the severity or type of wound or the need for treatment should contact a doctor. Minor wounds, such as scrapes and small cuts, may not require a visit to the doctor. However, anyone who experiences a larger wound or a wound that does not stop bleeding after the application of gentle pressure should contact a doctor for a full diagnosis and treatment. Wounds that cover larger areas of the skin, such as road rash , may also require professional medical attention. These require proper cleaning to prevent contamination and infection. |
| What to Expect During the 4 Stages of Wound Healing | Why Do Scabs Itch? Basic Principles of Wound Healing. Your wound may look red, swollen, and watery at the beginning, any may have a red or pink raised scar once it closes. Different types of wounds are treated with different suitable methods but if you have a wound that seems to take months or more to heal or if your wound healing process starts slowing, it could be a sign of a serious condition. Moreover, they trigger a complex and dynamic healing process. Complete regeneration can occur in pathological situations in tissues that have good regenerative capacity. |
| 28 comments | What your body does: Organizes cells and strengthens the new tissue. How long it takes: Anywhere from three weeks to two years, depending on some of the factors listed below. But as time goes on, the tissue will fade in color and flatten out. However, you may always have a scar. So, what are signs that a wound is not healing the way it should? Here are some things to watch for:. An infected wound can slow the pace of healing. If you think you have an infection, talk to a doctor right away, no matter how small your wound is. This will help reduce the chance of the infection spreading. The following are signs of wound infection:. While it can take up to a year or more for a wound to fully heal, it should start looking better after about a week. At this point the inflammation should be mostly gone and your body should be working on making new tissue. Slow-healing wounds are more common if you have diabetes , kidney disease, obesity, high blood pressure or vascular disease. The following may be signs that a wound is chronic:. So, pay attention to all your cuts and scrapes, no matter how tiny. Although chronic wounds are most common in people with diabetes, kidney disease, obesity, high blood pressure or vascular disease, you can have a chronic wound even if you are otherwise healthy. Your wound may heal faster if you keep it clean, moist and free of bacteria. Using antibiotic cream and keeping it covered with a bandage can help. Some truly interesting details you have written.

How wounds heal Wound healing is the physiological process the body uses to replace and restore damaged tissue. The body uses two mechanisms to heal: tissue regeneration; and tissue repair. Tissue regeneration Tissue repair Tissue regeneration is when the body replaces damaged tissue by replicating identical cells. Stage 2: the inflammatory response The second stage is divided into an early and a late inflammatory response. Neutrophils play an important role in the healing process. They kill local bacteria, which helps to break down dead tissue. They also release active antimicrobial substances and proteases an enzyme that catalyses proteolysis , which start debridement i. the removal of damaged tissue. In the late inflammatory response , approximately three days after the injury, monocytes another type of white blood cell appear. Monocytes are important because they mature into macrophages, large cells that eat bacteria, dead neutrophils and damaged tissue. They also secrete growth factors, chemokines and cytokines. In this way, macrophages play an important role in wound healing and fighting off infection. Stage 3: proliferation During this stage, macrophages produce a variety of substances that cause the body to produce new tissue and blood vessels — a process called angiogenesis. Stage 4: re-modelling Re-modelling starts already in the proliferation stage and continues for an extended period of time. How long does it take for a wound to heal? An effective dressing should: conform to the wound bed; have antimicrobial properties; absorb excess exudate from the wound bed; protect the wound edges and periwound skin; maintain a moist healing environment ; be comfortable and cost-effective; and be easy for the patient to remove and care for.
