Het begrijpen van een Oedeem

Oedeem is een medische term voor zwelling. Lichaamsdelen die opzwellen van letsel of ontsteking. Zij kan afhankelijk zijn van een klein gebied of het gehele lichaam. Medicijnen, infecties zwangerschap, en vele andere medische problemen kunnen oedeem veroorzaken.

Oedeem gebeurt er als uw kleine bloedvaten “lek” en laat vloeistof in het omringend weefsel. Die extra vloeistof bouwt, waardoor het weefsel zwelling.

Edema is also spelled œdema is an abnormal accumulation of fluid within the interstitium, located beneath the skin and cavities of the body. They typically cause severe pain. The amount of interstitial fluid is determined ermined by the excess of fluid homeostasis, and the higher discharge of fluid into the interstitium or impaired removal of the fluid can cause the condition.

Classifications of Edema
Cutaneous edema is also referred to as pitting when, after pressure is applied to a small area, the indentation persist after the release of pressure. Peripheral pitting edema, as shown in our picture, is a more common type of edema, resulting in water retention. It can be generated by systemic sicknesses, pregnancy in some females, either directly or as a consequence of heart failure, of lokale aandoeningen zoals spataderen, insectenbeten, tromboflebitis, en dermatitis.
Non-pitting oedeem worden opgenomen wanneer de uitsparing niet wordt voortgezet. Het is gekoppeld aan voorwaarden die lipoedeem, lymfoedeem, en myxedema.

Oedeem opgewekt door ondervoeding definieert kwashiorkor een acute vorm van jeugd eiwit-energie ondervoeding die door oedeem, prikkelbaarheid anorexia en een vergrote lever met vette infiltraten.

Een stijging van de hydrostatische druk optreedt bij hartfalen. Een daling van de osmotische druk occures in nephronci syndroom en lever faiure.

Oorzaken van Oedeem
Dingen zoals een verstuikte enkel, bijen steek, of een infectie van de huid zal veroorzaken oedeem. In sommige situaties, zoals een infectie, Dit kan effectief zijn. Meer vocht uit de bloedvaten zet extra infectie te bestrijden witte bloedcellen in het opgezwollen gebied.
Edema can also come from other diseases or from when the balance of substance in your blood is off. Bijvoorbeeld:

Low albumin: your physician may call this hypoalbuminemia. Albumin and other proteins in the blood work like sponges to retain fluid in your blood vessels. Low albumin may contribute to edema, but it’s not normally the only cause.

Allergische reacties: Edema is a part of the most allerg

ic reaction. In response to the allergen, adjacent blood vessels leak fluid into the affected area.

Barrier of flow: If drainage of fluid from a part of your body is blocked, fluid can back up. A blood clot in the deep veins of your leg can trigger leg edema. A tumor blocking the flow of blood or another fluid called lymph can cause edema.

Critical illness: Burns, life-threatening infection, or other critical illnesses can cause a reaction that allows fluid to leak into tissues almost everywhere. Ths can cause edema all over your body.

Hartziekte (congestief hartfalen): When the heart weakens and pumps blood less efficiently, fluid can slowly build up, creating leg edema. If fluid buildup occurs suddenly, fluid in the lungs, identified as pulmonary edema, can develop. If your heart failure is on the right side of your heart, edema can originate in the abdomen, as well.
Liver disease: Server Liver Disease (such as cirrhosis) causes you to retain fluid. Cirrhosis also lead to low levels of albumin and other proteins in your blood. Fluid drips into the abdomen and can also cause leg edema.

Nierziekte A kidney condition described as nephrotic syndrome can result in severe leg edema and sometimes whole-body edema.

Zwangerschap: Mild leg edema is typical during pregnancy. But serious complications of pregnancy like . deep vein thrombosis and preeclampsia can also cause edema.

Cerebral edema (Brain edema): Low blood sodium (called hyponatremia ), head trauma, high altitude, brain tumors, and a block in fluid drainage ( know as hydrocephalus ) can cause edema. Verwarring, hoofdpijn, unconsciousness, and commas can be symptoms of cerebral edema.
medicijnen: Many medicines can cause edema, inclusief:

  • Calcium channel blockers
  • corticosteroïden (methylprednisolone and prednisone)
  • Pioglitazone and rosiglitazone
  • NSAID's (such an ibuprofen and naproxen
  • Pramipexole

When they cause swelling, usually it’s mild leg edema.

Edema Mechanism
Six factors can contribute to the formation of edema
1. increased hydrostatic pressure.
2. reduce collie or oncotic pressure within blood vessels
increased tissue colloidal or oncotic pressure
increase blood vessels wall permeability
obstruction of fluid clearance in the lymphatic system.
Changes in the water retaining properties of tissues themselves, Raised hydrostatic pressure often reflects retention of water and sodium by the kidney


Symptoms of Edema
Your symptoms will deepen on the amount of edema you have an where you have it.

Edema is a small area from infection of inflammation (similar to a mosquito bite) may cause no symptoms at all. Aan de andere kant, a considerable allergic reaction (such as from a bee sting) may c cause edema on your whole arm that can irritate display tense skin, pain and restricted movement.

Food allergies and allergic responses to medicine may cause tongue or throat edema. This can be life-threatening if it complicates your breathing.

Leg edema can cause the legs to feel heavy. This can affect walking. In drama and heart disease, bijvoorbeeld, the legs may easily weigh an extra 5 naar 10 pounds each. Severe leg edema can impede blood flow, leading to ulcers or boils on the skin.

Pulmonary edema causes brevity of breath and sometimes low oxygen levels in the blood. Some individuals with pulmonary edema may have a cough.

Treatments of Edema
To treat edema, you often must treat its underlying cause. Bijvoorbeeld, you might take allergy medicines to treat swelling. Form allergies.
Edema creates fluid drainage can sometimes be managed by making the drainage flowing again. A blood clot in the leg is treated with blood thinners. They remove the clot to get drainage back to normal levels. A tumor that blocks blood or lymph can sometimes be contracted or removed with surgery, radiation or chemotherapy.

Leg edema linked to congestive heart failure or liver disease can be treated with a diuretic (sometimes called awater pill.Like furosemide (Lasix)
Edema you can urinate more, fluid from the legs back into the blood. Limiting how much sodium you eat can also help.
