Lipohypertrophy is a medical term that refers to a lump under the skin caused by accumulation of extra fat at the site of many subcutaneous injections of insulin. It may be unsightly, mildly painful, and may change the timing or completeness of insulin action.
Veterans who can't do a significant amount of work may be eligible for a 100% disability rating based on unemployability, even though they could not be rated 100% disabled under the Schedule for Rating Disabilities. The VA calls this Total Disability for Individual Unemployability (TDIU).
The number of disabled veterans rated IU and the cost of their benefits have risen sharply in recent years. From fiscal 1996 through 2005, veterans rated unemployable tripled from 71,000 to 220,000. In the same period, IU payments jumped from $857 million a year to $3.1 billion.
