"Diane Ladd died of acute-on-chronic hypoxic respiratory failure after years of lung issues," - the death certificate clarifies.

What is mentioned in the death certificate? In Ladd's case, the death certificate clearly states that the actress had interstitial lung disease, which had been going on for years beforehand. Esophageal dysmotility was listed as another significant contributing condition.

Ladd was cremated on Nov. 10, according to the record.

What Is Hypoxic Respiratory Failure?

According to Cleveland Clinic, hypoxic respiratory failure occurs when there isn't enough oxygen in the blood, which is often caused by a lung condition. Some of the most common symptoms of this seriously fatal health condition include -

  1. Severe shortness of breath or difficulty breathing
  2. Rapid breathing (tachypnea)
  3. Confusion, restlessness, or agitation due to low oxygen to the brain
  4. Bluish discoloration of lips, fingers, or skin (cyanosis)
  5. Rapid heart rate (tachycardia)
  6. Fatigue or exhaustion
  7. Chest tightness or discomfort
  8. Headache or dizziness
  9. Inability to speak in full sentences
  10. Low oxygen saturation levels on pulse oximeter

What Is Esophageal Dysmotility?

As mentioned in the death certificate, the second contributing factor in Ladd's death is esophageal dysmotility. According to NHS, esophageal dysmotility is a serious health condition where the esophagus - the tube that carries food from the mouth to the stomach, suddenly stops working and this leads to an acute lack in the proper movement of the foods. This mainly happens due to abnormal muscle contractions or nerve signals. This can lead to difficulty swallowing, chest discomfort, regurgitation, or food getting stuck.

It's not a single disease but a group of disorders affecting esophageal movement, including conditions like achalasia, diffuse esophageal spasm, and scleroderma-related motility issues.
