PER CURIAM.
      Arkansas inmate Tom Henderson appeals the district court’s1 dismissal of his
42 U.S.C. § 1983 action. Following de novo review, see Moore v. Sims, 200 F.3d
1170, 1171 (8th Cir. 2000) (per curiam), we affirm, see 8th Cir. R. 47B. We agree
with the District Court that Henderson did not state a claim, as he did not show
defendants were deliberately indifferent to his serious medical needs, see Estelle v.
Gamble, 429 U.S. 97, 104 (1976), or to conditions posing an “unreasonable risk of
serious damage to his future health,” see Helling v. McKinney, 509 U.S. 25, 35
(1993). We also conclude that the magistrate did not err in denying Henderson leave
to amend to add claims challenging his conviction, as he requested a sentence
reduction and thus the claims would be barred by Preiser v. Rodriguez, 411 U.S. 475,
489-90 (1973) (habeas corpus is exclusive remedy for prisoner challenging fact or
length of confinement). See In re NVE Corp. Sec. Litig., 527 F.3d 749, 752 (8th Cir.
2008) (de novo review of denial of motion to amend complaint based on futility).
Finally, we conclude that the district court did not abuse its discretion in denying
appointed counsel. See Phillips v. Jasper Cnty. Jail, 437 F.3d 791, 794 (8th Cir. 2006)
(standard of review). We also deny as moot Henderson’s appellate motion for
appointed counsel.
