What Factors Can Affect Wound Healing?

Wound healing, whether caused by an accident or surgery, usually proceeds consistently through a series of stages. Chronic wounds are those that do not heal within 30 days. Chronic wounds typically stall in one or more of the wound healing stages. Here are seven of the most prevalent factors influencing chronic wound healing.

Patient's Age

There are several general changes in healing capability that are age-related. According to studies, adults over the age of 60 may have delayed wound healing due to variables related to physical changes associated with senior age. In addition to many comorbidities, there is a reduction in the body's inflammatory response, a delay in angiogenesis, and a delayed epithelialization process. Some obvious changes in the skin are connected to melanocyte alterations, such as age spots, as well as drier skin due to reduced sebaceous gland activity. Reduced collagen production is also linked to delayed scar formation during the wound healing process.

Wound Type

The features of a wound can influence how quickly it heals. Larger wounds take longer to heal, but the form of the wound can also influence healing time. Linear wounds heal quicker than rectangular ones, while circular wounds heal the slowest. Furthermore, wound healing is slowed when necrotic tissue, desiccation, and foreign bodies are present.


Bacteria, viruses, and fungi can enter the wound site through any skin breach. Normally, white blood cells and other immune system components engulf and remove these infections. When an infection is present, it can spread to the surface and cause a sore or lesion that must be treated with appropriate wound care and sometimes medications.

Chronic Illnesses

Patients with diabetes or disorders that impact the circulatory system may have impaired wound healing. Efficient wound healing needs adequate blood flow, and chronic disorders that impair blood flow to the wound site may necessitate therapeutic intervention. Individuals suffering from chronic wounds should visit a medical practitioner for a thorough evaluation to determine the best treatment options.

Nutritional Deficiency

Poor nutrition in a chronically unwell or geriatric patient might leave the body with inadequate resources to repair the wound. Inadequate nutrition can develop because illnesses raise an individual's protein and calorie demands. Furthermore, wounds can discharge considerable amounts of protein on a regular basis, particularly in the case of severe pressure ulcers (injuries) or leg ulcers. When calories are inefficient, the body may break down protein for energy, diminishing the body's ability to repair even further.


A lack of moisture at the wound's surface can impede cellular migration, reduce blood oxygenation, and significantly delay wound healing. Dehydration caused by a lack of salt or water can cause all parts of the healing process to be delayed. While most individuals require 64 ounces of fluid per day, a person recovering from a wound will require additional fluid to aid the process of white blood cells getting to the injury site to deliver essential oxygen and nutrients. A well-hydrated patient will have urine that is clear and odorless.

Inadequate Blood Circulation

Because blood transports the required components to tissue for wound healing, patients with low blood pressure or vascular illness may have delayed healing. Blocked or restricted blood arteries, as well as heart, kidney, and lung illnesses, can all create problems in the body distributing important wound healing components, such as white blood cells and enough oxygen, to injured tissues.
