More than just cosmetic imperfections, when left untreated varicose veins stages can present serious health issues. Enlarged, twisted, and sometimes painful veins can be veins causing chronic blood lacks mainly in the legs due to weakened or damaged valves responsible for normal blood flow. From small irritants, sometimes ignored, varicose vein conditions can develop into serious complications, even becoming life-threatening. 

1. Chronic Venous Insufficiency (CVI)

The most complicated and common result of untreated varicose veins was that these people eventually got chronic venous insufficiency. This occurs as blood flows less well back to the heart, causing such blood to stagnate in the legs. Over time, there will be continuous formation of swelling, changes in the skin, and ulcers in the legs. While venous stasis ulcers should be included in the very first ones mentioned, these are perhaps the worst to treat. These indolent ulcers can then become infected and threaten the person's overall health.

2. Pain and restricted mobility 

Pain becomes characterized with burning, throbbing sensations, as well as heaviness about the legs, with prolonged sitting or standing aggravating symptoms. There is, therefore, interference with many daily living activities that affect mobility and impact quality of living. In very extreme condition, it may course cramps of muscles and/or restless leg syndrome. Both may disturb sleep and affect daily needs. 

3. Superficial Thrombophlebitis (STP)

Net, neglect for quite a long period would pave the way for naturally-occurring varicose veins stages to have a higher incidence that would later develop symptoms of superficial thrombophlebitis (STP). It then refers to a clot formation in the superficial vein of the skin with inflammation around the formation, thus leading to redness and pain. Compared to deep vein thrombosis (DVT), STP is not life threatening or death causing; however, it can sometimes turn out to be a big problem when the superficial clot moves into the deep veins. 

4. DVT or Deep Vein Thrombosis and PE or Pulmonary Embolism

Among the very nasty conditions one could grt from the untreated varicose veins stages would be deep vein thrombosis and then the traveling of clot from deep veins into lung circulation leading to pulmonary embolism. Essentially, this is formed as a result of the clot formation in a deep vein, mainly of the leg. Most unfortunately, many of the times this clot dislodges from its site and flies off into the substantia of the lung causing pulmonary embolism (PE), a very much fatal condition where a lot of people perish in a lucid of seconds. This should never be taken lightly; swelling, warmth, and excruciating leg pain could be indicative of an underlying DVT.

5. Spontaneous Bleeding

Varicose veins, which are swollen and are in close to the surface of the skin, may bleed spontaneously. Downward bumps can easily lead to risking severe blood loss due to the enormous pressure of these veins. In some cases, it might be uncontrollable and need immediate medical assistance.

6.Skin changes

Skin discolouration, thickening, and eczema-like rashes develop over time when varicose veins are left unattended. The skin becomes very fragile, tears easily, and this creates a venous leg ulcer. These ulcers are painful and slow to heal, whereas they are prone to infections, which increases the risk of cellulitis-an already serious condition that spreads into the underlying tissue layers. 

Conclusion

At first glance, varicose veins may seem harmless, but ignoring them can have far-reaching consequences where it concerns one's very own appearance. They can unfortunately give rise to very morbid complications termed chronic venous insufficiency, deep vein specialist doctor thrombosis, ulcers, and even life-threatening pulmonary embolism. Early medical assessment and treatment-whether medical or lifestyle changes, compression therapy, or minimally invasive procedures such as endovenous ablations could be used to significantly mitigate or eliminate these insidious threats and greatly improve vascular health.
