A "misunderstood" mother-of-two died just weeks after completing cancer treatment and being given the all-clear, an inquest has heard.

Suzanne Dowdell, from Norwich, died in hospital in April this year having suffered a cardiac arrest at her home. She was 57 years old.

An inquest into her death heard that seven months before she died she had been diagnosed with throat cancer, for which she had been receiving radiotherapy.

But she completed her treatment and was declared cancer-free just a matter of weeks before her death.

In a statement read to Norfolk Coroner's Court, her daughter said: "My mum had a lust for life and was recovering well - although she was often frustrated at being misunderstood.

"I saw her most days and we had been celebrating her being cancer-free."

But on April 6, after not being able to reach her mother, Miss Dowdell went to her home in the city to find her unresponsive.

CPR was performed and Mrs Dowdell was taken to the Norfolk and Norwich Hospital, where it was discovered that she had suffered a hypoxic brain injury as a result of a cardiac arrest.

She died in hospital on April 9.

Mrs Dowdell had struggled with a long history of intravenous drug use and alcohol misuse for which she had been receiving support from Change, Grow, Live (CGL).

A report from the substance abuse charity confirmed she had been receiving prescription methadone to help with her recovery, with the ultimate goal of stopping drug use.

Yvonne Blake, area coroner for Norfolk, said: "We know she had a previous history with illicit drug and alcohol misuse.

"She was with CGL at the time and it was agreed she was doing rather better."

Mrs Blake concluded she had died a drug-related death, with pathologists believing her cardiac arrest was brought on by a combination of drug and methanol toxicity.
