Why do wounds and scratches heal for a long time

Scratches and wounds occur due to a violation of the anatomical integrity of the skin and mucous membranes as a result of mechanical stress. The most common occurrence of abrasions, scratches and wounds - careless handling of piercing and cutting objects in everyday life and at work.


Poor blood clotting - the cause of non-healing wounds


If the skin and underlying tissues are damaged, the blood vessels located there are affected, so wounds and scratches are usually accompanied by bleeding. Normally, the blood stops being released after 1 - 3 minutes under the influence of platelets - blood cells, which have the ability to increase blood viscosity and “stick” the wound.
If the bleeding has not stopped within 15 minutes, the cut is very deep or with torn edges, you should immediately consult a doctor.
If the bleeding does not stop, it indicates a violation of the function of blood clotting.The cause may be leukemia, hemophilia, insufficient platelet activity, taking anticoagulants. Poor blood clotting causes any scratch or wound to heal for a very long time.

Influence of infections and diseases of internal organs on wound healing


Often the danger is not the wound itself, but its infection with pathogens. Bacteria usually enter the wound due to non-compliance with the rules of first aid.
First aid for wounds and cuts is the removal of foreign bodies, the treatment of the wound surface with an antiseptic, the imposition of a sterile dressing.
Microbes that have penetrated the subcutaneous tissue provoke the development of the inflammatory process: the wound begins to fester, redness and swelling form around it, and the temperature of the affected person rises. Suppuration leads to the fact that the period of wound healing is significantly increased.
Sometimes wounds and scratches do not heal for a long time despite the correct treatment. The reason in this case can be determined by the therapist, focusing on the results of clinical studies. The following diseases and pathological conditions exist in which wounds and scratches do not heal well:
- diabetes;
- oncological processes;
- anemia;
- lack of vitamins and microelements;
- disruption of the immune system.
A person with these diseases disrupts metabolic processes in cells, which impairs the ability of tissues to regenerate. Sometimes long-term healing of injuries is a temporary phenomenon that can be observed due to a decrease in immunity after ARVI and other infectious diseases. If the problem of recovery from injuries is systematic, you need to consult a doctor for a full examination and a correct diagnosis.
